Furnace was working before in our 2017 27' FB FC. Search thru the forums and found things to check. We have two AC units. Furnace control is on zone 2. Below is what I checked this morning when outside temp. is the low 60s, and trailer is connected to shore power.
1. Make sure control temp. setting is above indoor temp.
2. Propane is not empty - able to light stove, a constant blue flame.
3.
12V fuse for furnace is good. Checked with a DVM at fuse panel. Voltage measured is at 13.1V
4. Zone 2's HP is able to start - thermostat should be good.
5. Put Zone 2 in auto mode. It kicked in HP but not furnace
6. Powering off and on thermostat control, go to FURN mode - no go.
Next I tried to open the furnace panel outside the trailer to check wiring and sail switch. But I am not able to open the furnace panel after removing the 5 screws and the 4 screws that secure the hot air exhaust,
. I tried to pry open with a flat head screw driver but it will not open. I must not be doing it right here. How should the furnace panel be opened?
BTW, two weeks ago I upgraded the stock 55A converter/charger to a PD9200 series. All equipment work after upgrade. Since I had to disconnect the battery and shore power for the upgrade, is there a reset switch I need to press to restart the furnace? If so where is the reset switch located?
Heading to Pinnacle this weekend. Temp. going to drop to low 40s. Hopefully the furnace is a simple fix. If not, will have to bring a space heater and more covers since HP will not work when outside temp. is too low.
