I recently had a new Affinity system installed in my home. Everything has worked fine and the comfort factor is way up from the 20-year-old unit it replaced.
The last two days, around 5 pm, the sun is setting (my condenser is on the south side of my house) outside temp is about 65 ish. My thermostat makes a call for heat, the blower starts in the air-handler, but the outdoor unit (compressor and fan both) do not start. The blower continues to run and run, but the outdoor unit never comes on. No strip heat turns on either. I have to manually satisfy the thermostat by lowering the set-point to the indoor temp, or turning the thermostat to the off position. Once I do either of these, I can raise the temperature set-point back to where it was, or set the stat back to auto, and the system resets and runs as it should.
I have called the HVAC company, they are planning to make a service call and address the issue. BUT, I want to be armed with knowledge so I can quiz the tech and make sure my problem is identified and addressed. SO, here are my questions.
I know there are temperature sensors on the outdoor unit. Could this be locking it out if it senses the coil temperature is too high to safely operate? If so, how can this feature be managed to prevent my system from shutting down and not operating until it is reset?
