    I have a 1994 Trane XE90 furnace that just started doing the same thing. It will heat up and run okay for a while but after a random number of normal cycles, the blower won't shut off. I have to shut the furnace off and restart it to get any heat. Sometimes I can see the burners start to light but stop or misfire.

York furnace code 7


The error 7 shows that the gas failed to ignite. That is because the sensor does not sense any flame. This can be because the sensor is dirty. You should look in the area of the jets for a wire that may be purple in color. It attaches to a bare metal probe that is shaped like the letter L This probe extends into the path of the flame from the jets. When it detects flame it tellls the controller that everything is good. When it gets sooty or dirty from use it cannot detect the small electric currents that are present. Clean it with scotchbrite. Error 7 means that the furnace is locked out and wont restart for an hour. You can shut the power off and turn it back on to reset it.

Furnace turns on but no blower, furnace turns off in a few minutes.


I am not familiar with this unit but It sounds like the thermal switch that turns on the blower (bonnet control) has failed. There is also a safety that will shut it down if it does not detect the appropriate air flow in a short time. You can check here for more information on the blower: http://www.tommark.com/FascoDraftInducerCrossReferenceGuide.pdf

Getting fuel in oil on 19hp b&s motor. Cleaned carb and drained oil, fresh oil and started motor, motor ran for 3 or 4 minutes then had to use a little choke to keep running and then it started...


How long did it take to do this job..did you clean the the carb first...then the oil or vise versa...the reason I as is ma y if these motors are equipped with an electric valve on the carb that go bad or stuck allowing the gas to continue flowing after shut down eventually in the intake valves and into the crankcase...causing smoke and high crankcase pressure and out the carb and exhaust...no use changing it WILL happen again..the fix is simple put an inline gas shut off and shut it off if only shut down for minutes...happened to my 18 horse Briggs...just shut it off every time you turn the engine off..Hope this helps..good luck..

When turning on heat after a period of using air


It sounds like the fan limiter switch is going bad. This switch waits until the air temp is high enough for heating the house before allowing the fan/blower to come on. There is another switch that shuts off the blower when the air drops to a certain temp, or it may be the same switch that does both jobs. Hope this helps.

Furnace will run, put out heat, turn off and doesnt start again.


What is model # & serial # of this furnace, it may have a diagnosis led indicator light located on the control board, behind bottom door of furnace which will blink and tell you a fault code. Also check furnace filter, make sure its clean, check through out the house to see if all registers are open and not blocked by any objects, make sure cold air return grill is not blocked, the unit could be over heating and shutting off on high limit, good luck.

My furnace is in a 1994 manufactured home. It is


i think it is your fan because when it is supposed to come on (when hood is hot enough) it won't,...and when the gas valve doesn't get the o.k. from the fan that it is working, the unit will shut it self off so it doesn't over heat. Gas boilers and furnaces have alot of safety things like this,....see if the fan has an oiling place on it. I've seen control panels cause this too,....replace whatever is cheapest first. good luck

My york diamond 80 can be fired up, but it is shut off automaticaly after approx. 20sec. This can be repeated 3 times. I beleive the fun and borad panel are working fine.


The flame sensor might have dust build up on it. The flame sensor makes sure that the system has ignited before it starts the main blower. If it ignite and burns for 15-20 seconds then goes out that is most likely your problem. Identify a probe that is in the direct path of the flame(usually in the last burner tube from the gas source), it will have one wire coming off of it and usually has one screw holding it in place. As time goes by the sensor will get a build up on it and stop functioning. Turn the power to your furnace off, then remove the screw and then gently pull the flame sensor out. Using a MILD abrasive like panty hose of paper towel (DO NOT USE sand paper) clean the sensor and then put it back into place. Tighten the screw and then turn your furnace back on. That should fix your problem.

No heat through vents


Does your condo have more than one thermostat? if so there are powered dampers that open and close to direct heat where it's being called for. You may have dampers stuck/inoperative.
