Nest Randomly Blows Cold Air During Heat Cycle

mfutterman — Mon, 06 Feb 2023 03:39:52 GMT

So I bought a home in Jan 2023 and installed Nest in Feb 2023 - Things seemed okay in Summer, however when Winter came I noticed that when running the heat, once every other week it would all the sudden blow cold air during the heat cycle - it would display that it is still 'heating' with the orange screen, but cold air would come out (and would run nonstop).

I called a HVAC repair and they cleaned my pilot light sensor - but the issue is continuing. When I open up my heating/AC unit and then close it (I guess restarting it) the issue seems to be fixed for a few days and the heat will come on again, but trying to figure out why this keeps happening. Is it the nest? the wiring? the furnace?

I have gas 'air handler' from Weather King - and attaching the wires for my original and how the nest looks now

Any help is greatly appreciated!
