Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
Mt Honeywell central air conditioner unit will not turn on, neither the fan or the the air conditioner. We returned from vacation and the unit seems "frozen".
Sounds like it may have lost power. Check the breaker and the fuse at the furnace. If they are all in the on position and working then it sounds like you may need a technician. If the display is blank on the thermostat you may also want to replace the batteries.
