I have a York heatpump, outdoor package unit last week the weather cooled down and we switched the t-stat off, last night I noticed the emergency heat light was on, I switched the t-stat to cool and the air handler comes on but not the compressor, and the emergency heat light remained on. I cycled power on the unit and after about 1 or 2 minutes the emergency heat light came back on. What's up can anyone help me??

Check your breakers going to the a/c unit. If your heat pump faults out the aux heat takes over. If you change it back to cooling will the heatpump run?

Does your thermostat have a switch to put it in emergency heat? Some of the older stats had this switch.

Yes it has but the emergency heat light stays on in off, cool, heat positoins and we are trying to cool but the compressor want come on the air handler will.

Take the cover of the t-stat off and plce a jumper between the R terminal and the y terminal if the compressor comes on remove the jumper relace the cover and turn the t -stat to cooling with the temp lowered enough for it to come on if it does not come on the tstat is bad
