Check with the manufacturer. Many times these companies offer accessory kits for such application. You will need unit Model #.

Try jumping the two thermostat wires together to see if the heater starts. If so, replace your thermostat. If not, jump the two terminals where the thermosta twires attach to the furnace. If it starts, you have a bad thermostat wire or connection.

SOURCE: Clare Megasave Propane Furnace. A.C. compressor

You probably have 2 temperature limit switches in thefurnace. One turns on the blower once it is hot enough when the furnace comeson. The second one turns off the gas if the blower fails to come on, or it getstoo hot for some other reason. If the blower fails to start, the gas will keepcoming on until the upper limit switch shuts it off.

Some furnaces use a different relay and coil for a higher speed for fan onlyand A/C is you have it. This means the problem could be the relay too. Most ofthe controls on newer furnaces except the limit switches, are on a board makingdiagnose and repair difficult. In that case you may need to replace the board. Hope this will help you. Good Luck.

How do I reset the temp my heat pump switches from electric to gas. It runs much more economically on electri than on propane. The thermostat is a Honeywell th8000. Code 350 setting I believe. Thanks

Heatpumps are more complex than an AC unit. Yes, there is a difference between a heatpump and an air conditioner. Where the real difference lies is out side in the condenser unit. There's a defrost board out in the unit, and depending on the brand and model, one of the wires will need to be changed so that the gas furnace will not come on. The problem with this, heatpumps use the heat that is available from the outdoors and transfers it to indoor. When the temps outside drop below 50 degrees, there's not enough latent heat to transfer, thus calling the propane furnace to operate. Without the addition of the furnace, you will not be able to heat the area properly. The only way to remedy this, is to remove the propane furnace and replace it with an electric airhandler with a heat strip for "emergency heat". The emergency heat term is used when the temps drop below the temps I mentioned above and calls for the heat strips to come on.

Rvp thermostat

After you replaced the batteries, you also need to sync the remote with the receiver for it to work again. Here's the manual link: http://www.atwoodmobile.com/manuals/furnaces/MPD%2033179%20SP%201.08.pdf

RVP 8000 A/C just experienced slight power surge. Compressor on.

I'm leaning toward sticky relay as well, but if you want to confirm it's not thermostat, remove thermostat from wall, and temporarily disconnect the yellow wire from thermostat (compressor) when/if, it happens again. If compressor stays running, I'd say relay for sure.
Just for future reference , Gray wire from thermostat is low fan, green wire is high fan, yellow is compressor, blue is ground. ( For cooling side) The red is 12 v + to furnace and white is negative to furnace.(heat side)

Cozy wall furnace (propane) does not respond to thermostat. The pilot is lit. Furnace is 3 yrs. old and rarely works. The wire to thermostat is 20 feet.

Try jumping the two thermostat wires together to see if the heater starts. If so, replace your thermostat. If not, jump the two terminals where the thermosta twires attach to the furnace. If it starts, you have a bad thermostat wire or connection.

I'm replacing an old thermostat with a new Honeywell RTH6300B programmable. I have propane heat and central AC. My old thermostat has a black, a red and a yellow leads with no ID on the old thermostat wall...

Open up the propane furnace and see what color wires are hooked to the gas valve or circuit board. If it has a circuit board, note which color is on the R terminal and W terminal, Connect the the thermostat the same way. Most likely the yellow wire powers your A/C so you can hook that one to the Y terminal.

Open limit switch

Tjere is a limit switch that will only allow the durnace to reach a certain temp by kicking on the fan. The thermostat being unable to read the temp affects its ability to keep the furnace from exceeding your settings. *Advise not to use until corrected. Both limit switch and thermostats are inexpensive and simple to change. If in doubt, call a heat and AC tech to repair.

Short cycling

There are a few reasons why your furnace is restarting after it reaches temp. and shuts off. First, if you have a mercury bulb thermostat it needs to be level and the heat anticipator needs set properly. If you have an electronic thermostat then you need to make sure the DIP switch settings inside are set properly for propane. If you have a digital thermostat there are also settings to be made for your type of heating. These settings will be explained in the thermostat installation instructions. Also, Make sure your furnace filter is clean. If this does not help then there are some other things to check which may need to be done by a technician depending on your mechanical aptitude. Hope this helps!

Furnace problem

The problem is most likely in the control module of the roof air unit. Dometic uses the thermostat to activate and deactivate a relay in the control board of the roof ac unit whiich is just visible when you remove your air intake screen. The two blue with white stripe wires are the furnace control wires.

The furnace turns on and off by the opening and closing of relay. Most likely, the furnace control relay is stuck in the on position. On the thermostate, remove the fur wire and see if the furnace quits afrer it cycles down...it does not quit right away. With the termostat out of the loop, if the furnace does not shut down, the problem is in the control box. They are not hard to replace but you must be careful with the live wiire from the 110 ciucuit breaker. If you are not comfortable with the repair, take it to a dealer. The part number is on the assembly box. They need to know if you have the heat srip option or whatever othert options our Roof AC has. If the furnace still runs with the blue/white wires disconnected, the furnace wires are shorted somewhere between the furnace and the AC control unit.
