So, I just moved into a new house with a Trane dual fuel HVAC system. The house has stayed comfortable these past two weeks since we closed.
One thing I don't understand though. On that 27 degree morning when the E Heat would have kicked in (and may have) the "E Heat" indicator didn't show as such on the digital thermostat. It just said "heat", not "E heat". Nor did the E heat light come on on the control panel over the actual HVAC unit in the attic.
The compressor unit outside has been running, and tonight made noises like it was trying to run, but the fan wasn't spinning, then it stopped humming, and a thumping noise started from the outside unit.
I went inside and manually switched the thermostat from "Heat" to "E heat" which fired up the gas heat, indicated E heat on the thermostat, as well as on the control panel over the HVAC unit in the attic, and eliminated the noises at the seemingly struggling unit outside.
Oh, and the power was blinking this afternoon but seems fine now. I get a heads up on power fluctuations, even if the lights don't blink, due to my computer UPS clicking on and off.
Anybody knowledgeable able to tell me how much of this is out of whack?
