Question about Honeywell Programmable Thermostat Heater
I have a Honeywell thermostat (10/12 years old?). The green power light
went out along with all the digital readouts. I replaced the batteries and all the digital readouts came back but no power light. I checked the main breaker and all the breakers are on. The AC is not responding to the thermostat. Any idea what can be wrong?
I just had this happen to me a few days ago. I hope you find this response before you did what I did and paid an AC guy $103 for him to do about 5 minutes worth of work. Here goes.
The power is shutting off because your drip line is clogged. Your drip line is the tubing that goes from your compressor (inside) to the outside of your house. When that tube gets clogged up (with algae and dirt) then the water will backup in the line. There is a protection circuit in the line and when it detects water (because of a backup) then it shuts all power to the AC off. If you take a shop vac outside and **** all the **** out then you'll be fine. The AC guy said that when I replace my filter every month that I need to pour about 1/2 cup of bleach in the line (from the inside) to prevent algae from forming and stopping the pipe up. Hope this helps someone out there before it costs them a $100.

Testimonial: "It is a touchscreen. I have seen references to the battery being round and lithium CR2450; however, not sure if this is accurate. Does anyone know?"
