Have you checked the flame rollout switches? Some have to be reset manually. You would also find out why they are tripped.

Gas valve will onley open when I put ajumper wire on limit switch


You will need to replace the limit switch if it has stopped working. But if it is still working, it is protecting you against over temperature conditions and is part of a safety circuit. One the biggest causes for limit switches to open is the lack of air flow due to blocked coils, dirty filters or improperly operating fans. You should never operate a furnace with a safety circuit overridden.
You mentioned it started when jumpering a safety switch, if it is the flame rollout switch then most rollout switches have a reset button between the leads on the switch. Reset the switch is easy and should allow the furnace to restart. The rollout switch detects just that excess heat coming backward into the flame sword area. Some causes for this to occur is cracks in the heat exchanger, the induction fan deteriating so the flue gasses are not exhausted properly, or a blockage in the flue gas path. Blockage can be caused by excess rust buildup in the tubing, dirt dawber nests, and any number of other obstructions.
Any way you need a professional to determine the cause for the limit switch opening.
Hope this helps.

Why condenser won't start board flashes6times meaning open rollout


check your roll out with an ohm meter they should have continuity if not they have a reset button on top of the switch push it and this will reset them. If they don't have continuity they are open.

Rollout switch is open?


You possibly have a Flaming out problem. Your "One" time rollout sensor needs to be replaced, then the reason for the rollout needs to be identified! Very Important! Get a qualified heater service center out to diagnose this problem. Don't just replace the rollout sensor. Sometimes these are called Fusible Link.

If you didn't reset the rollout switch, the air will not work. The rollout switches are in the furnace burner secton. Look at the burners, the rollout switch(es) are just above the burner. They will have a button on top to push for reset. These rollout switches will generally have two wires going to them.

My furnace turns off and I am getting an alarm OPEN ROLLOUT. I reset it and work for 6 hrs, 3 hrs and last time worked 2 days straight.What could be the problem


Hello, a rollout switch opens for several reason, a damaged heat exchanger,lack of combustion air, impoper gas input. I would have a technician come out and check these three things.

Rollout switch continues to trip


If you have a cracked heat exchanger this will cause the flames to rollout and trip this switch. Its meant to stop the furnace from running and putting carbon monoxide in your home. Watch the furnace as it tries to light if when the gas valve opens and flame is established it should go into the tubes heat the heat exchanger and then your main blower motor will come on. When your main blower comes on is usually when you see the flames rollout and trip that switch. If this happens you can either buy a heat exchanger or new furnace if its a older unit Obama still has that awesome tax credit til 12-31-2010.

Coleman home heater stops working fault code "limit switch open"


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.
