Help Heat Fridge and Toilet issues

[bar081474]

I recently loaned my pop up to a friend for a short time and I get it back and now after fixing several things they had broken, I find that the toilet water isn't flowing out when I press the button. Also the heater isn't lighting and blowing.. and the refrigerator I have it on gas the pilot light is lit but it is not getting cold. Never loaning it out again... any advice on how to fix it would be appreciated...

Thank you

Wild guess is that the board controller or pump for all three of those is electric (DC12V). Is there a fuse panel? Batteries in good shape? All the other 12V works (lights etc)?

Can't help much without knowing the make/model of those items. However, it sounds like all those items are lacking 12v power to make them operate. I'd start by checking battery & fuses & wiring.

Yes it's all 12 volts the refrigerator obviously is a three-way fridge works on gas 12 volt and electric the battery has plenty of charge but has some corrosion all the lights are coming on

It's a Rockwood similar to the one above however it is fully loaded, all fuses are good lights work battery has 2 wires going to each contact battery has a little corrosion.

Lights working does not equal good battery! Measure it with a voltmeter.

The lights may still light when the battery is too low to run other things.

The pump should still run on a depleted battery but slower than normal so I'd use a multimeter to check whether 12V is reaching the pump and troubleshoot backwards if it's not there.

For the fridge, I know you said the pilot is lit but if you turn the thermostat to make the fridge colder does a full flame come on? The pilot itself isn't enough to make it cold. If you can't get a full burner flame tell us your make and model number.

What is the battery voltage if read with a meter between the positive and negative posts?

Ok so i got everything working other than the heater.. i have 2 full tanks and a fully charged battery i even had it connected to my vehicle while it was running and tryed it to make sure it had enough power..

It originally started by blowing clicking then nothing. BUT it only did this once.. now it does nothing when i turn it on.. no fan no click nothing, i have checked all the fuses and breakers any trouble shooting tips maybe it is something stupid i am missing

What brand & model furnace is that? Suburban like the t-stat? They all work generally the same, but the details vary. I've written a Furnace Troubleshooting article (it's in the forum Resource library) but it's geared to the DSI type furnace and yours may be pilot ignition.

Basically the furnace gets its 12v power directly and that powers the circuit board and fan. The thermostat sends its +12v to the furnace as a signal to start the fan and the ignition process. Both the furnace 12v and the thermostat 12v have to be present to get it started.

Double check that the tank is full of water. If it got winterized (drained) and is in bypass it won't stay lit.

That's a Suburban NT20S furnace. These manuals should help.
