Furnace not working
« on: October 12, 2017, 11:39:03 AM »
Took the MH to a local shop to fix the furnace on our rig as it is completely unresponsive to the thermostat.  The little flame icon appears when you ask for heat, but no ignition, fan, nothing.  They just called to say they can't figure it out.  Will probably take it to the factory when I can, but does anyone have any ideas in the meantime ?  Can a separate thermostat be installed just for the furnace ?  BTW,,, the shop said they got the furnace to run from directly at the unit and it ran that way perfectly.

Yes, you could have a separate thermostat just for the LP furnace. (My coach has two LP furnaces, one with it's own t-stat and one linked to the heat pump in the main t-stat.) Having a separate t-stat would not allow the heat pump lock-out mode that kicks on the LP furnace to work, but that wouldn't be a big deal in my opinion.

I am puzzled as to why the shop can't "figure it out." I would think that any competent shop would be able to determine whether or not the t-stat is sending the required signals to the furnace. It is possible the t-stat is defective, but they need to do some routine trouble shooting before starting to throw parts at it. I guess it is good that they admitted they can't figure it out rather than starting to do solutions that cost you $$$ and may or may not fix it!

Thermostat was replaced this summer for an A/C problem, so chances are that it is good. They did say that the thermostat signals are not reaching the furnace.  They said something about a secondary thermostat being in the system somewhere,,,, ??

If they cant figure it out they shouldn't be touching it. I would back track. They may have miss wired the thermostat when they worked on it last time. There are not that many wires controlling it so if a broken wire is suspected, bypass it. They already answered their own question and proved it when they jumped it directly at the furnace. I dont want to call them idiots but.....            What is the  model number.

What does your thermostat look like? Does yours control the heat and ac on the same thermostat?

Is it like this?

Yep,,, thermostat controls both a/c's and the furnace.  Will try to work thru the manual but I am really a plug and play kinda guy, or if a wire is broken or disconnected I am a genius.

If your furnace works off the same thermostat as the a/c, chances are the heat-needed signal goes through the a/c zone controller. Almost guaranteed it does if you have heat pumps or multiple heating/cooling zones in the RV. Odds are both of those are true in your coach.

The signal to the furnace is simple - just +12v on a wire that [eventually] reaches the furnace. But if the wire goes to the zone control first, it may have been disconnected there, or conceivably the zone control board is faulty (rare).

What thermostat is it, and do you have multi-zone and/or heat pumps?

Thermostat is an RV Comfort.ZC.  Yes it controls everything with 2 zones. but the gas only works off the front a/c.

I'm not finding a great link but this one seems to also show a control box. Since yours is dual heat it may be relevant.  The control box looks like it ties into the generator start system.

Looks like a fuse in that thermostat




FUSE
The thermostat is equipped with a replaceable fast acting 2-Amp fuse located on the base of
the thermostat.  The fuse is designed to “open” if the appliance is mis-wired or there is a short
in the system.  If the fuse opens, the cause of the failure must be located and corrected before
the fuse is replace

Took the original thermostat apart and if there is a fuse in there it is not like any fuse I ever saw.  Everything on the board is soldered into the board for sure.  The replacement thermostat looks exactly like the original.

Look for a fuse on the base of therm. Check it with a low power test light or ohm meter. You mentioned your capabilities early. A visual inspection is a first step and then you start a process of troubleshooting. Most important is to not use any jumpers or accidentally shoot power to a circuit that blows out a control board or something. There is a point where you need to realize your limitations and maybe find a different repair facility.


Edit: Ok we were both typing. Is there a little door or plate or anything on the bottom?

Yep,,, I am  definately at my limits, so before I put 110 volts to a 12 volt system I will put my hands up.  Just have to stay above 40 degrees this winter which usually isn't too difficult in south Texas or Arizona.  Thank you for all the ideas and imput.

Dont give up yet. :) I was looking for a pic of the fuse location and only found this so far. Looks like it resets the system too.

Some problems can end up being something real silly. Read this and go back to reset and reprogram.  BUT I dont want you to end up with nothing either......so dont reset it if you cant program it.

Read through these posts as merc talks about checking connections in the control box and an green led coming on. Be careful of 120 volts from shore power possibly.

I have the same thermostat.  On a couple of occasions it has gotton lost or lost its program. If I remove the thermostat from the wall and unplug it or a few seconds, it resets to normal.

If the thermostat was replaced recently, it may not be unusual to find it defective from the beginning, especially if the furnace start was not tested at the time of installation. I went through two new RV Comfort thermostats that had defects before getting a third good one several years ago. Fortunately they were all on warranty.

It's simple enough to check for the +12v signal on the heat line from the t-stat. If it does that, the t-stat is ok. If not...

There are a couple variations of the ZC model thermostat, e.g. an 83xx series and a 93xx. The 93xx uses an infrared remote sensor, so I'm guessing the 83xx is wired.  In any case, I believe the white wire from the t-stat is the heat signal in all of them, and also the earlier HC model.

It appears that one of the circuit boards on the furnace is malfunctioning and when I looked for circuit boards on Amazon, it was the first one that popped up.  That might tell you something.  Will report when we get it installed.

Well,,, plugged the new circuit board in and, you guessed it, didn't fix the problem.  Really has the tech puzzled as power comes in to the board, but does not come out,,, same as the old one.  What are the chances of two boards being bad in exactly the same way.  Troubleshooting specs say, if this occurs, the board is bad.  He is going to try to talk to someone at Suburban next week to see if he can get some advice.

There are inputs and outputs. You need a schematic that splices all the systems together and be able to look at the whole system showing the furnace, ac, control box, generator etc and how they are connected together. There is a sequence of operation. You look at the sequence of operation and go step by step looking at the components and what inputs they need. If you find that the inputs are ok but a card isn't putting out it mat be because it needs to see other certain things happening.

Have you set the furnace manually to "Gas" operation which seems to bypass the heat strip function?

Exactly, and that's a shame. I had to help one RV "tech" figure out which solenoid was the battery mode solenoid (the house disconnect solenoid was nearby.) The kid was really thrashing around and had no organized approach to problem solving.

Uh,,, as far as I know, there is only one way on the thermostat to run the furnace, but it really doesn't matter right now as the furnace is out of the coach and sitting on a bench in my garage.  If the tech can't figure it out, there is a Suburban service center not too far from here.  Maybe they can bench test the unit.

I may not be following along correctly but didn't they do that at first? I'd have to go back and look but does you furnace harness plug have four wires? 12 volts pos and neg plus two blue thermostat wires?

After reading the thermostat link again I go back to the control box led that should be on. It says that if it's not lit there is a 12 volt problem. As owners of the RV we have to learn the systems but the tech could be going around in circles and burning money on parts if he doesn't understand it.  You need a tech who knows the therm and be able to walk you through it. Maybe the service center has someone who can go over the thermostat with you.

We do have 12 volts at the furnace when we call for heat.  Power goes all the way to the board we replaced but does not come out so it appears that the thermostat is doing it's job.  We tested the on off switch that is on the furnace itself and it is working properly. What you said earlier that it is still not receiving a signal somewhere is the most probable issue.  But what signal ?

The control board has two "12v out" functions: (1) start the fan in response to the thermostat, and (2) open the gas solenoid once the fan is up to speed. Are you saying the fan doesn't come on?   Nothing  else even tries to happen until the fan comes on and gets up to operating speed (determined by the sail switch). Then there is a short delay for purging the burner before the gas valve opens and ignition is attempted.

If the fan doesn't run, you have either a bad fan or bad wiring path to it.

Your original post said the shop determined that the furnace runs "directly" if the thermostat is bypassed. Now you are replacing circuit boards and saying no 12v out of the board? Doesn't make any sense! Both of those things cannot be true at the same time.

Gary,  originally, the shop said that the furnace worked when they powered it up "directly".  What that meant I am not sure.  I would bet, knowing what I know now is that they got the fan to run.  Today we got the furnace to run and throw heat by jumping wires at the furnace itself.  We also determined that the thermostat is sending the proper signals to the furnace.  Three of the wires do not go to the furnace and supposedly go to a heat isolation relay somewhere in the return air plenum. The 3 remaining wires at the plug,at the furnace, other than the white wire do not come from the thermostat.  Whew,,,, I think I have that right.

Thanks for the follow up post and I hope your winter is comfortable. It's great learning material. I'd try to get schematics of the  thermostat, furnace, ac unit and control box and plenum and anything else all put together in one place. I have copied and increased the size of  pages of schematics for various pieces of mobile equipment and taped them together. It made a nice fold out map when trying to troubleshoot. 

The good thing is that now you are at square one. It may be best if you learned  the system and keep others fingers out of it. Find out where all the sensors etc are. While looking at your issue it did seem like a good number of posts were about resetting the thermostat. You need  to be able to program and reset before assuming any repairs are needed although I do understand how it is when we dont put our hands on some of these gadgets regularly.

Luckily I knew a local HVAC tech who was willing to look at the furnace and did not give up until he found the problem.  The best thing was he came to my house 5 times to work on the rig as we progressed through the issue.  A couple of false leads were followed but he and I both learned a ton through the process. You are certainly correct when you say it is important to know as much as you can about these machines, as you never know when it may come in handy,,,, Thanks !!

... I'd try to get schematics of the  thermostat, furnace, ac unit and control box and plenum and anything else all put together in one place. I have copied and increased the size of  pages of schematics for various pieces of mobile equipment and taped them together. It made a nice fold out map when trying to troubleshoot. ....
When our coach was new, I printed out all of our plumbing and wiring diagrams and put in a drawer. Rarely do I need to refer to them thank goodness.

Winnebagos schematics leave a lot to be desired as even when I talked to a tech at Winnebago, he had a very hard time telling me where some relays were hidden.  He expressed that he wished they had the old schematics to help locating various items.

We have a 98 Itasca sunflyer.  I cannot even get the blower to turn on when in heat mode on thermostat. If I switch to cool I hear it come on.  We are at out wits end. It's getting cold now

Baileyracing99 ... Welcome to the forum.

You will get much better responses if you start a new thread when you start a new topic rather than doing it one that already exists.

If I understand you correctly you are trying to turn on the blower from the thermostat when in heat mode. That blower is for the AC / heat pump. The thermostat has electric heat mode, and gas heat mode. When in the electric heat mode the blower comes on only when the heat pump calls for it after the compressors start, and the air will come out of the ceiling ducts. You cannot manually turn on the heat pump/ac blower when in either heat mode. If you are running the gas heat, the lp furnace will come on and the furnace blower should come on with it and the heat will come out of the floor ducts.

Thermostat was replaced this summer for an A/C problem, so chances are that it is good. They did say that the thermostat signals are not reaching the furnace.  They said something about a secondary thermostat being in the system somewhere,,,, ??

Did the furnace ever in it's whole life ever work?

Did it work right AFTER the new thermostat was installed?

Who installed the thermostat and what was the original problem with the air conditioning?

1. Yes
2. No
3. A local RV dealer.  Front A/C did not work at all.

I think I'd go back to the RV dealer and explain that the furnace doesn't work and the problem started when they fixed the A/C.

Actually, I did do that and they said they couldn't figure it out.  I believe I stated that before.

Didn't realize it was the same RV place.   What is the name of the RV dealer? I don't want to go there!

Don't really want to badmouth them as they are good folks but just a bit short on diagnostic abilities.  They worked at it for 3 hours and did not charge me anything for their time.  Turned out to be a fairly difficult problem to find and they really had nothing to do with it.
