View Full Version : Heat Pump Aux Light Blinking
03-01-2005, 05:05 PM
I have a Rheem heat pump that is 12 years old (the compresser was replaced 1/2004). I have noticed over the past couple of several weeks that the aux light on the thermostat is blinking. If I tap temp up a degree or two, the light comes on steady. If I tap it down a degree it to, the light goes off.
The fact that it is blinking, should I be concerned?

The defrost board in the OU is bad. Put the t-stat on em-heat and call your serviceman in the morning. If you go outside to the condensor, you will here a clicking that is timed with the light blinking.
If you let it go too long you run the risk of burning up fan relay and reversing valve.

Is the thermostat loose on the wall. Any vibrations against the wall??

The thermostat is not loose in fact I checked that yesterday as well as making sure that it is level...
Thanks for the advice (both of you!)...
