20 Most Recent Honeywell RTH230B 5-2 Day Programmable Thermostat Large Questions & Answers

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.

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

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.

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 !!

don't know but honeywell technical support may know
check if it has a safety switch in the base as it may not be making contact with the surface the fan is sitting on.
It has a timer maybe cause ?
if not in usa then go to honeywell in your country and then look for help at bottom of web site.
