Down in S. Texas and this cold snap has required use of gas furnace as roof heat pumps could not keep up with cold temps. Have some issues would appreciate your input on.
First night we woke up with mh 54 degrees. The heatpump running and gas furnace not running. I changed tstat setting to gas and gas furnace came on and slowly warmed mh. When tstat satisfied at 68 degrees furnace shut down but would not restart when interior temp dropped. I had to cycle tstst off and back on and furnace again came on.
I have tried the gas furnace a couple times since and occasionally it will cycle normally once or twice but then require cycling off to work.
So 2 issues as I see it.
1. Gas furnace not coming on when heatpump not able to maintain temp.
2. Gas furnace not cycling properly to maintain temp.
Could this all be the thermostat? Unit under warranty but no dealer within 100 miles so trying to see what the experts out there think.
Thanks,
