Our heat won't come on. The AC cooling side on thermostat works but the heat side won't come on. At first the #1 unit was all that would work on cooling and now the # 2 unit will work on cooling also,...
06 Pace Arrow, worked good till this trip. Back unit quit first,front would work on cool. last night when tried to turn on heat pump or furnace the heat side would not work on front or back. while fooling with thermostat the back unit started working but the heat side still won't work. Has a RV Comfort.zc thermostat. Have plenty of gas. Now both cooling units are working, but no furnaces or heat pump. RV Products AC & Heat pump units I think Coleman. Thanks for the help!!
