If the thermostat does not have a loose or broken wire coming from your unit than the transformer in the unit may be bad. A transformer is used to step down the power to usely 24 volts or less and is used to run the controls in the unit as well as to power the thermostat. The transformer should be easy to spot. If you are familar with the use of a maltiemeter frist check for the incomimg 110 or 220 volts that should be coming in. Next check the power going out of the transformer. If you have control power at the unit than check it at the thermostat. Some units have a fuse that you can replace. Make sure you turn off the power before doing any work. Hope this is helpful.
