I have an Intertherm electric furnance downward flow. The furnance with chased after running for a while ‘and relax after 1 min. I had a company come and look, but would not kick out when they were here. I had the one-reel and cleaned the fan and still kicking on the outside, but only sometimes, if the door is open on one or two inches. If I leave the door out of the furnance is running fine, and if I put the door on it completely kicked out after 20sec everytime. I need help. . . . Ok I replaced the filters, that r clean house is a prefab returns only a door-ventilated, that is pure. A / C coil is on top of the furnance and brought out to clean it, they pulled out the fan down and cleaned with a solution of acid. I see that has two switches of the fans, where can I find them? The filter is one that puts the apartment through a coil.

Turn off the water heater and any other gas appliance and see if the furnace will ignite (with the door on) It may be the gas pressure and the door off may be allowing it to get more oxygen.
or
If the vent, or intake has anything in it partially cutting off the air flow the thick exhaust gas compounds the problem. By it running with the door off I would suspect the intake side of the system. If it has two vent pipes coming off it figure out which one is the intake (the one that doesn’t get hot), and take it loose from the unit and see if it will run with the door on then. Check the filter too.
But operating a furnace with the blower door off
or ajar can allow combustion by-products to mix with
the air that is circulated to heat your house. This is not a good thing.

Mar 20, 10 at 10:34 amYou are saying inter therm so I am guessing that this is mobile home or manufactured home?
If the door is off and the furnace is running ok then let me ask you this?
Does this furnace door have the built in filters? Is it the old blue type of filter?
If this is it then I say you have dirty filters these furnaces will not run proper with dirty filters.
Either way buy filters that will fit in the door and replace them if this is the case.
Correct me if I am wrong but let me know either here or by contacting me
Good luck

Mar 20, 10 at 11:37 amsounds like an air flow problem.could be filters. or you could have your return grills throughout your house covered up . somehow your not getting enough air across your heating elements. make sure all your returns are open and clear, or your limit switch may be weak and needs replaced

Mar 20, 10 at 11:54 amThere could be a few problems
1- You could have a bad sensor kicking it off a hvac repair company should be able to fix this type of problem
2- If there is an air flow problem your heating elements could be getting to hot which will shut it down
3- A result of poor air flow could be that the coils have warped and are grounding out on some part of the inside of the furnace
Replace your filter and check cold air returns (all vents) and keep them wide open If this does not help it’s likely a sensor or a grounding problem
