Heating, Air Conditioning, Fridge, HVAC/2006 12 seer heil unit not working


I have a 2006 heil split unit. Does not come on. I have 240 volts to contacter but coil will not energize and pull in.

You need to use the same meter and determine where you are loosing the 24v.
Check to see if you have 24 on the contactor coil.
If you have a heat pump, is there power on the defrost board?
Then work your way back to the air handler and then the t-stat.

I have been in the HVAC field for the past 18 years. I can help with most HVAC questions. I work on commerical buildings for the most part, and have yet to find anything I could not troubleshoot and repair, when repairable. I work on small 1 ton units to a 2500 ton chiller. Troubleshoot air flow, elect, and control problems. I attend regular classes to keep up with the latest and greatest.


I work on commerical sites, hospitals, gov't buildings. I can troubleshoot just about anything in the HVAC business.

5 years trade school, VFD training classes, Liebert factory training, some York and Trane factory training.
