“Arcoaire RPJ II starts up and shuts down” , posted Fri 12 Oct 11:05 ______________________________________________________________________ Hi everyone Last year I had our Arcoaire RPJ II serviced twice because it would start up then shut right back down. I had heard of the glowplug issue before, so it was no surprise when the technician scraped it off, charged me $100, and said that should do it. The next guy replaced the thermostat for another $125. I knew the problem wasn’t totally fixed but then it was spring so I gave up. Now the problem, of course, is still here; and we want to start heating the house! Gotta love procrastination. It seems to only happen under certain conditions, and I don’t think it’s a glow plug. If the temperature of the house is 66 and the thermostat gets set to heat to 70, it works as expected and runs the burner for a while until the temperature is reached. If the temp of the house is 66 and the thermostat is set to 66 or 67, it will fire up for about 30 seconds, then shut back down, wait a minute, and keep doing it over and over. When it stays on, it heats the house properly and I can see the pretty blue flame happily burning away inside the furnace. When it gets stuck in the loop I’m not sure it’s heating the house well at all because last winter when this happened it was 50 in here. Does anyone know where I should look to make this thing behave normally? I would expect the heater to stay on for several minutes at a stretch until it’s heated the whole house by a couple degrees, then shut off for a while until it cools again. I can’t think that this constant turning on and off is good for the heater and it really isn’t effective at heating the house. Thanks for any help! I’m not a service technician but I’m trying to research this becuase I can’t pay this heater company over and over to take shots in the dark, at least if I know what I’m probably dealing with then I can clue in a qualified technician if it’s something I can’t fix myself.

If your stat is a older style mercury and not digital you have a heat antisipator, that should be set to your furnace, if it is not set correctly you end up with the same problem you are having now, take the cover off and there should be a gold arrow and some #’s the arrow can more, move it to the longest possible setting, there will be another long arrow showing you which way to the longest or longer cycle, place it there and see if that fixes it.

Best way to tell is to pull the thermostat head off and jumper the red and white wires (or the R and W terminal – wires colors might be different). That will remove the thermostat from the loop and if it runs fine, that would be your problem. d0s4d1 “Re(3):Arcoaire RPJ II starts up and shuts dow” , posted Sat 13 Oct 01:28 ______________________________________________________________________ thank you both! So . . . . probably a bad thermostat or improperly set thermostat? It’s a digital one, I (apparantly foolishly) bought it from the repairman used. I guess I need a new one . . . . . *sigh*…… thank you for pointing me in the right direction :)
