I had a similar problem a while back on the same type unit in a different apartment except that time it was the AC side of the unit. Any help would be appreciated. Thanks in Advance.

Look at your theromstat, does it have a small switch marked AUTO/ON ? What position is the switch? I would not worry because your current setting is what I set mine at 24/7/365. It uses only a little more electricity and makes the home more comfortable.

Hi Ballengerb1,

Thanks for your response. The Switch on the thermostat is on auto.

Could be a bad switch or something bigger on the mother board. Based on what I said about running 24/7 I personally would not bother with further repairs.

So what is the reason you waited until now to mention the system is not heating? My answers so far are all based on what you said was the problem, the fan runs all the time.

Hi Ball,

The system has been working fine in heat mode this winter up until the fan came on and wouldn't shut off the day I posted the original question. The fan runs constantly in Heat mode, maybe even in AC mode (didn't check), therefore it blows cold air when the limit switch is activated.

Thanks again
