Climma Heat

Mike Ondra

I have seen a number of posts on Climma unit heat cutting off 10 to 15 seconds after being turned on, but no solutions. Sounds like overheat protection control failure. This even when filter is removed to attain maximum air flow, and still cuts out at all fan speeds. (Might be instructive to know if it cuts out more quickly at low speed than high speed as that would indicate that there is at least some feedback in the high temp cutoff control.)

Has anyone determined a cause? Thermistor failure? Relay issue? Wiring short or break?

Solution? Part replacement?
