AC Blower Stuck On?
« on: February 03, 2018, 07:23:40 AM »
Hey all.  I have a 2018 Montana 5th wheel with two heater/AC units and it had it hooked up to house before winterizing it and the front unit's blower seems like it stuck in the on position.  Tried turning the thermostat on and off and even down but the blower just keeps running.  The only way I can turn it off is to unplug electric or flip the breaker off.  Anyone have an idea what's going on?  Thanks in advance for any help.

Two things I can think of:
1. Did you wait long enough for the thermostat to cycle when you put it in the off position?
2. Do you have only one thermostat for both roof unit's? There maybe a reset switch/button on the base plate. Pull the front off but do
   so at your own risk, I assume no responsibility for my lack of knowledge. 8)

It could be set to on instead of auto.
Do you have the dual zone controller ?

Thanks guys.  Answer to main question.  There is only one control for both units.

When I turn our furnace, fans or AC/heat pump units on or off, there's a delay of about 20 to 30 seconds before they actually respond. Like seabreeze331said, I was wondering if you're giving the system enough time to respond.

Thanks guys and yes I left the power cord attached for a good half hour.  Each time I plugged back in boom blower comes on.  Scratching my head.
