I replaced the battery to honeywell RTH230B. Heat won't turn on.

I followed a comment from a previous source and reversed the polarity of the batteries. I then flipped them back to the correct position and the flashing battery indicator went away and the thermostat functions correctly.

My Honeywell RTH230B flashes a snowflake them the fan shuts off and

Hello, the snowflake flashing is a (supposed to be) 5 minute delay to prevent short cycling of the compressor. This delay can sometimes get stuck thus requiring replacement. To test , remove top of thermostat to where you can identify wires and terminals. Have someone stand near the ac unit for this test, and then take a wire or paperclip and briefly touch Rc to Y. This should start the outdoor unit. R to G will start the indoor fan

I changed the batteries and now there is nothing displaying on the screen. The air conditioner is working.

Contact Honeywell and see if there is some sort of reset for unit.

Wont turn off a/c still works

You have to take the cover off and get inside and unhook a wire. You may have 3 wires unhook 1 and if that doesn't turn it off hook it back up and unhook the next. One of them will turn it off!! Then go to the hardware and get another thermos!! You won't get a shock or anything cause it's not hooked up to any power source, they are just sensor wires. I don't know much about Honeywell, I just know I don't like their thermos. Had one once and had nothing but trouble w/it !!

My rth2300 honeywell thermostat says the heat is on but the heat is not on.why?

It could be the breaker is tripped or the blower is not getting power. Check your transformer to make sure you are getting 24 volts going to the fan relay sequencer and make sure you check your capacitor that is connected to the fan as well. sounds like a minor electrical hiccup. Also check your thermostat wires and pay close attention to anything marked w1 or w2 as these are the terminals that control the heating part of your system.

Can a Honeywell CT87N switch from Heat to Cool on its own? Twice now I noticed it was cooler in my apartment and I went to thermostat and it had been switched from Heat to Cool on its own...

That's very unlikely. I'd sooner believe the cat has been playing with it or it gets changed when someone wearing a backpack brushes past it (sometimes the straps or zipper pulls snag the oddest things). You can get a thermostat guard to prevent this if your landlord permits it.

I need to change Trane Weathertron Baystat 239 Thermostat over to Honeywell RTH6360D 5-2 Day Programmable Thermostat?

Question edited for clarity. Installation manual, but it has some very specific requirements. You may not have the correct one. The RTH6360 thermostat does not support L/A, S, or U terminals. If there are wires in terminals that are not listed, you will need additional wiring support. Visit yourhome.honeywell.com/support to find out if the thermostat will work for you. I don't understand that, and if you don't, you need a heating or electrical engineer.

Replacing a 2-pole baseboard heating thermostat

Here at home where I reside we have an old school thermostat that has the mercury bulb that acts like a sensor, and in other cases it could just be as easy as replacing the batteries in the unit itself, usually a lid that hides them, sometimes it works

My Honeywell oil-filled heater will not stop heating at the chosen temperature, but rather goes all the way up to 80 every time.

Probably a faulty thermostat. Time for a qualified engineer to take a look or to replace it.
