Go to zone 3 and see if any air blowing out. Likely have a stuck damper. If you can access the dampers tap on the duct or motor a few times, maybe free it up.

There is a Honeywell model RTH2300B1012, which is what I think you're talking about.The Honeywell website has the owners manual for that model available online at:http://customer.honeywell.com/Honeywell/getliterature.axd?LiteratureID=69-2448ES.pdf

To replace it, you'll need to know whether it's a Robertshaw or Maxitrol Valve. As well as the Model number of the valve and whether it's Natural Gas or Propane Gas. Unless, you're really experienced with working on gas appliances, I would not recommend this as a DIY project.

Hope this helps solve your problem.

so replace it

There are a couple of things to check. There is a water pump in the unit that draws the water and pushes it through a tube into the pad area. The tubes can get plugged or the motor on the pump can fail.

Question moved from Cars and Trucks. It is probably a thermal cut out, or high limit fuse. Difficult to get a replacement if you don't know the model. It will be one of these. https://www.google.com/search?q=Honeywell+tower+fan&rlz=1C1QJDB_enCA643CA644&sxsrf=APq-WBvNOfIR9Bt5E8PbqGY3Gr60wOZmuQ:1647889201437&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjZ_-vT8df2AhVJXM0KHWJtC7gQ_AUoAnoECAEQBA&biw=1920&bih=937&dpr=1 Then you can Google 'make model parts'. ..

I just dealt with this problem today. Put new batteries in and still blank but then I noticed that there was acid buildup on the negative connection for the batteries so I cleaned it off with a toothbrush and lemon juice. It fixed the problem

Four screws in the back, take them out to open unit. At the very top is a circuit board, tale the four screws out of that and carefully take circuit board out. You will see the tip over sensor (TOS). Flip board over to find the little metal ball for it, solder that metal ball to the one next to it.

Get the common hooked up on both indoor unit and tstat and be done with batteries all together!!!

This was our first home in 2014, built un1981. Not sure when KozyHeat was installed. but since when within the last few days the remote and local seemed to disconnect completely. We tried several dozen times about the gas local to remote to pushing the flame button, all to no avail. Is it the transmitter? Is it the remote? Is it something else? We live in Northern Albrta, so it has been a little tricky to keep the heat in the house consistant. Please reply with good news. A replacement or repair or anything?? Thank yoy!

air condition

If the board isn’t shorted out then a damper or tstat is. I would first take a pic of all the wiring, turn power off and remove all damper wires. Turn power on and see if you get any lights. If yes then you can eliminate one damper at a time to find problem. If no lights, turn power off, remove remaining wires other than the transformer wire that provides power to board and then power on. If you get lights then you likely have a tstat issue. If still no lights you have a bad zone panel.

Likely don’t have the common hooked up inside unit.

Replace the battery. The Triangle and exclamation point mean the battery is in need of replacement.

There are other universal replacements but if it was me I would stick with the honeywell parts. I know they are more expensive but in your instance where you already have a problem that is causing the control panels to fail I'm afraid you would make it worse by using other then factory replacements.Thank you
