Question about Coleman Propane Forced Air Heater w/Electronic Ignition (50,000-80,000 BTU)

Rollout Limit Switch Keeps Tripping

I just had a guy out yesterday who replaced the Rollout Limit Switch on our Coleman/Evcon home furnace.  This morning, the furnace kicks on but only runs for about five minutes before you can hear the click of the switch tripping and then the gas flame shuts down.  I can manually reset the switch by pushing on the top of it, but that only repeats the procedure.  Thoughts?

    Dead on, brother.  We had the meter upgraded when they put the pool in last spring; must be pushing too much.  I throttled back the gas valve a bit tonight and it's working normally.  One related question: as the gas is firing into the four chambers w/in the heater core, you can see the vertical fins and it looks as though they're degraded quite a bit.  Is that the result of too much gas/flame or is that just an old Coleman/Evcon on its last legs?

IF YOU LOST POWER WHEN FURNACE WAS RUNNING IT TRIPPED ROLLOUT SWITCHES AND POSSIBLY THE HIGH LIMIT . IN CENTER OF ROLLOUT SWITCHES IS A LITTLE RED BUTTON THAT YOU RESET . YOU CAN ALSO TRY FINDING HIGH LIMIT WITH POWER SHUT OFF TO FURNACE PULL BOTH WIRES OFF HIGH LIMIT AND USE PAPER CLIP TO JUMP BETWEEN THE TWO WIRES MAKE SURE YOU DONT SHORT OUT AGAINST ANY METAL WHEN YOU TURN BACK ON IF IT WORKS YOU NEED A NEW HIGH LIMIT SWITCH.

Reset the switch. Check the heat exchanger thoroughly for blockages, cracks or holes. Check induced draft motor for proper operation. Check flue pipe and chimney for obstructions.

Furnace blowing cold air after replacing limit switch


Limit switches are safeties and require a manual reset. They are also a Normally Closed contact. A hi temp. thermostat operates on its own. If you are sure it is a limit, find the red little button and listen for it to click. Sometimes they push pretty hard.

i hope the heater doesnt come on when a limit switch is open,you really have problems. so a limit is telling you that your furnace it over heating. first check filter and heat vents and returns they must be clean and open. closing heat vent or blocked returns will cause over heating. after chacking this look at firing rate. furnace could be overfired. you would need a "u" gauge to check manifold pressure. your name plate will tell you what this should be. find the tap on the burner manifold or outlet of gas valve. fire furnace and see what it is. 3.5"wc for nat and 10" wc for propane maybe.

How do you test a pressure switch and other limit controls?
This is for people who are experienced with electrical equipment and the use of a Volt Ohm meter. *Please never by pass a pressure switch or limit control. The pressure switch and limit switches are there for your safety. You would test by setting your volt meter to "Volts AC" and test the rollout switch by placing one meter probe on one terminal of the rollout switch and your other meter probe to a good ground. Have the red probe touching the top terminal of the rollout switch and the black probe touching a ground (body) of the furnace. You should be getting 25.85 volts which means the rollout is good on the top terminal. I would next test the bottom terminal of the rollout by touching the red meter probe to the bottom terminal on the rollout switch and the black terminal to ground. If I get 25.85 volts on the bottom terminal the rollout is good. If I do not get any voltage on the bottom terminal then the rollout has tripped and can be reset (if equipped) by pressing in on the little button or replaced. If your rollout switch is tripped you probably have a stopped up heat exchanger or a leaking heat exchanger. I would recommend calling in a service technician to find out why the rollout switch tripped. If you have an open limit control either the furnace has over heated or the limit has gone bad. Problems that would make a limit open up would be dirty filters, dirty evaporator coil causing a restriction in the air flow or a slow blower motor (check the capacitor on the blower motor to make sure it is good). A weak blower motor capacitor will cause the blower to run slow and eventually fail. Pressure switches, and limit switches can be tested with a meter in the same manner. With the furnace calling for heat you can test each of the terminals on the pressure switch to ground to make sure the pressure switch is closed. You should be getting between 24 to 28 volts from each terminal to ground if the pressure switch is closed. If the pressure switch is open you either have a stopped up vent, drain line (if you have a condensing furnace) or bad pressure switch.

My furnance is acting up you turn it on it clicks on then lights the flame gets big then seconds later the flames go out and the blower kicks on what could be the problem ive had several people look at it...


If the fan takes too long to come on, the high temp limit may be opening. Could be a defective limit, hard to say without more info. Another possibility is a mis-adjusted heat anticipator. A normal setting would be around .45 amp. The heat anticipator is inside the cover of the thermostat (older, analog style). Good luck.

you probably have a cracked heat exchanger which is causing the rollout switches to trip.even the tiniest of cracks will cause the fan to blow the flame back into the unit and cause them to trip. check the heat exchanger for even the tiniest of cracks if so replace it. and be sure to have a carbon monoxide alarm in your home.
