Hello, We have the 5/2 Honeywell Programmable thermostat, and I would like to know how to reset the furnace filter reminder and flashing battery indicator. If memory serves me right, there is no battery for this unit, why is my light flashing? The digital indicator displays a flashing AAA like battery that is in two pieces?
Can you help ?
Sounds like a relay sticking. Possibly in the thermostat or possibly the furnace relay at the furnace. The next time it happens, unplug the thermostat from the wall. If the furnace still runs then it's the furnace relay.
Hope that helps...

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.

you will have to reprogram it according to the operating manual.
The manual is available on www.manualnguide.com

Good Morning, and yes you said it. Anytime a stat doesn't come on when it is set for a call for heat or cooling, the sensor on the subbase of the stat has lost its ability to sense the correct temperature. I have seen mechanical stats last as long as 25 plus years, but that's truly amazing for a digital stat to last that long. Yes, replace the thermostat. I don't know what kind of system you have, but if its a gas furnace with an a/c, the wiring will look like this. You will have terminals marked R, Red, for the 24 volt hot wire, G, Green, Y, Yellow, and W, White for heat. Going back to the red wire, it should have RC and RH on it. There will be a normally red wire connecting the 2 terminals.The Red wire coming in can connect to either one, as they are all together. The new stat will come with the new Red jumper wire attached. So, if you do have a gas heater, this is very easy to install. The only terminals you will need to use are RH to RC for the incoming red, Y, G, and W for heat. Y is for cool, and G is for fan. Very easy. Now if you have a heat-pump, they have many more terminals and can be a problem wiring them. If you have gas, forget the heat pump. I wont confuse you by going there. If it is a heat-pump, contact me in the comment box to let me know, and I can help you there also. Get a new stat at Home Depot, Lowe's Hardware, or O.S. Hardware. You want a 5 day, 2 day programmable Heating and cooling thermostat, 24 volts.It will have everything you need. See if it takes batteries for the display, they may not come with those, it will say on the box. Turn off your power to heater, so you won't short out the new one.They come in 2 sections, first the stat that just snaps on, and the subbase that is screwed to the wall. It will have the wiring terminals on it. Remove a couple of screws and loosen wires and remove. Be sure you write down how the wires go in case they used different colors, you never know. You will be all set. Store the manual in a safe place for future use. I wish you the best.

Happy Holidays to you and family!

Testimonial: "I hate spending money needlessly replacing items that may not be the problem. Thank you for confirming my suspicions."
You probably have a loose or broken wire to the fan relay. Check the wires on the thermostat first. Pull up on the bottom of the thermostat to remove it from the wall plate. You should see several screw terminals and the conductor wires that should be connected to them when you look at the wall plate. Check if any of the wires are disconnected or broken. If a wire is broken, strip a portion of the unbroken section of the wire and secure it to the appropriate screw. (The fan relay terminal is G for most setups.) If none of the wires are loose or broken, then you have to check for damage to the wires between your heating system and the thermostat or at the heating system. It could be a bad wire going to the jumper on control board or damage to the board itself.
I hope this helps. If the problem is not at the thermostat, you may need to have a professional diagnose and fix the problem. However, if you post additional comments about your heating system, Fixya experts may be able to help you diagnose the problem.
(we had the broken wires at the thermostat keeping the fan from working in the past. It's an easy fix if you are willing to handle small wires carefully.)
