Having problems with your Air Conditioners ?

I have a Rheem Gas Furnace with an old analog thermostat (Wires conneected to terminals R and 4 for the thermostat). I went to install a Rheem digital and programmable thermostat and it indicated that it would not work for that wire configuration (Instructions indicated that the thermostat would not work with wires to the #4 thermostat terminal). Is there a setting on the furnace circuit board I can change, or is there a digital, programmable thermostat one can use on this unit - Model RGDJ 12EA


Answers :

If you have 2 wire at thermostat Terminals at furnace that the thermostat wire attach to should be R & W if your new thermostat has R & W terminals is should work, an easy thing to remember is the red wire on R the white wire on W. If 4 wire at thermostat at furnace green on G, Blue on Y, red on R,and white on W same at thermostat If these do not match find a thermostat with these terminals

Purchased VisionPRO 8000 series model TH810U1003 digital programmable thermostat from Amazon on line to replace my old analog. My furnace company maintenance person was unable to get into the installation menu. It was not installed. Later, I managed to get into the installation menu and set the date and time but not all of the installation menu was available to me. I called Honeywell Support and they would not tell me how to get to the hidden installation menu items. They told me I would ha

I have a DuoTherm BriskAIr 13.5K BTU. The Dometic thermostat also controls my HydroFlame 8531-IV furnace. This morning, the furnace would not come on. I checked the wiring and there is no voltage at the thermostat blue wire on the furnace. If I jump 12 volts to the thermostat blue wire, the furnace works normally. Replaced thermostat; no change. I hear something clicking in the air conditioner unit when I switch the thermostat to furnace mode. I assume the A/C has a relay to control the thermost

Have atwood furnace and coleman mach thermostat and it would not shut off. I unplugged power to rv and had to hit battery disconnect so that it would stop.waited few minutes...turned on...heat would not come on but blower ran until I had to unplug and start over. Is it my thermostat?Then abut 3 hours later went through the whole process again...heat came on..all well....then heat shut off...blower kept going and could hear clicking noise from furnace, (trying to light) and would not work.


It may be your thermostat, but try this first to see if time delay relay may be sticking. When it won't shut off, turn propane off, and go outside and unscrew the 2 screws that hold your cover on, and lower the cover down. Look straight ahead, attach ... Coleman Mach III Air Conditioner

My heater is not working reliably. With the setpoint above the room temp, it may come on right away, or not for 12 hours. Pilot/igniter is ok, and will sometimes start the furnace heat going, then shuts off. New digital Honeywell thermostat, worked fine until 3 weeks ago. Thermostat says Heat when it's trying to turn on the furnace, but often nothing. Sometimes when it's starting up a loud buzzing sound comes from the furnace, perhaps a relay oscillating.

I have a duo-therm thermostat that I think is the problem. My a/c only works when the fan is swithced to the on position but does not work in the auto position, also the heater does not come on and work unless i tie a jumper line to the ground wire. I have been told that the problem could be the thermostat or the circuit board in the a/c. If I can I would replace the thermostat with a digital.


Try changing the thermostat out first. Make sure that you set the set switches in the thermostat for the proper medium you are using. If the unit is heated with gas make sure you set the thermostat settings for gas ( there is a small switch inside ... Dometic Rooftop RV Air Conditioner

There is a switch on my 1 1/2 ton Ruud furnace/Air handler that is not working properly. The unit would not turn on, even though the thermostat was working. I took the panel off of the air handler and found that a switch had been duct taped into the on position on the unit. Apparently, the tape had shifted and the switch was no longer in proper position. when i moved the switch, two green indicator lights lit up. When i turned the unit back on, the A/C worked. Clearly, there is a problem w

Townhouse has an old slide, mercury bulb thermostat. Our furnace is now cycling and the flame only takes a few seconds before it turns off again. Most of the time it just blows cold air. Last year we adjusted the anticipator higher and it worked fine. Now, we adjusted it to an even higher number and it still cycling on and off. 1) Right now I think the value is at .4.

I have a LUXPRO PSP600 digital thermostat and when I switch it to heat it automatically comes on. The hot air is blowing fine. However when it meets the temperature that is set, the heater turns off but the furnace in the basement for air circulation doesn't turn off. It keeps running. (The fan with the furnace in the basement kept running.) Any help would be greatly appreciated. Thanks in advance!

I have put many of those in and yes, they are hard to program compared to the new ones. You will probably not find any instructions unless you go on line to honeywell and ask. Otherwise it may be worth your time and less head ache to just go get a ... Honeywell Air Conditioners
