Question about Honeywell Programmable Thermostat Heater

Honeywell programmable Thermostat won't hold time or program

I woke up to find the furnace not running as it was programmed to do. The furnace was not running. We replaced the furnace circuit breaker. But the Thermostat keeps reverting to 1:00 p.m, or sometimes goes blank. When we reset day, time and temperature it runs for a while then reverts back to 1PM. The furnace works but not according the time and program we set and want.

Most thermostats use a six volt transformer for a power source, similar to a door bell, you can tell if yours does by looking at the wires that are attached to the thermostat.

The wires will be thin with just a single strand if you have these wires then you have a transformer, try and find the transformer (good luck) test it with a voltmeter if it fails the test that's it, if not, call the man. Probably it though.

Does thermostat have to be on Auto or On to make my heat come on?? Dont know if i have thermostat problem or Furnace problem. Furnace clix on whenever it wants to, doesnt use the schedule i have...


If the thermostat is wired correctly, and matched to the type of heat you have ie electric, heat pump, boiler, forced air, gas or oil, the heat should run in either Fan ON or AUTO. Maybe you can explain your system a little more in depth...furnace type, M#, & thermostat brand w/ M#.

Honeywell CT3400. New batteries but touch pad has become unresponsive


Turn the furnace power off for 10 minutes (the control wiring up to your thermostat is powered from a transformer in the furnace) & turn it back on. Make sure you have 24 volts to the Red wire on the thermostat.

Honeywell ct3200 thermostat won't turn on


DON'T BUY A NEW ONE JUST YET! IF THE BATTERIES DIED & THERMOSTA LOST POWER, IT MAY HAVE LOST IT'S MEMORY. IT MOST LIKELY WENT BACK TO FACTORY DEFAULT SETTINGS, & NEEDS TO BE RE-PROGRAMMED THROUGH THE INSTALLER SET-UP MENU. HOPEFULLY YOU HAVE THE PAPERWORK FOR THE THERMOSTAT STILL & CAN POSSIBLY DO THE SET-UP YOURSELF. IT SHOULD HAVE STEP BY STEP INSTRUCTIONS FOR THIS IN THE INSTALLATION GUIDE (NOT THE OWNERS MANUAL)

My furnace works intermittently.


You may have a dirty flame sensor. There are a number of other possible causes as well. Rheem/Ruud/Weatherking furnaces also have problems with the connection on the blower deck.
The flame sensor sometimes must be bypassed around the MOLEX CONNECTOR in the deck due to humidity.
Hope this helps.

My honey well thermostat keep clicking and I can't program it


If you have a programmable thermostat and it is a couple of years old you will probably have to install a new one. What kind of thermostat do you have? You can turn power off to furnace and then take thermostat off wall and take wires marked r & w and connect them together your heat should come on when you turn power back on. If not you could have blown the 5 amp fuse inside furnace. I would check the fuse inside of furnace. If you take panels off front of furnace you should find a controll board inside that runs furnace.If you have anymore question just reply back to me

New thermostat honeywell RTH7400 cycles oil furnace every 10 min.


rth7400 maintains a 1 degree differential in temp so 10 minute cycles are not unusual.
