The ignitor will light, the blower will start up and run for a few minutes and then the system will shut down, and the blower will continue to run and cool down. The ignitor is not working properly, the ignitor has carbon build-up and need to be removed, cleaned all the black carbon from the ignitor with a little piece of sand paper and replaced, turn the heat back on and this should correct the problem.

At night its shuts down when the therm is satisfied,but trys to restart right away and when it does start it shuts down right away and just keeps doing this


The thermostat has a differential built into the temperature sensing operation. The differential is normally a degree or more. If the stat shuts down at 72 degrees it should not start the unit again until the temperature in the room reaches 73. If the AC runs and cools properly until it shuts down, I would check the thermostat. The AC can not restart immediately after it shuts off because the pressures in the system are too high at the compressor. It takes a few minutes for the pressures equalize allowing the compressor to start. If the stat tells the unit to start under high pressure, the compressor will shut down on overload. It will start and run after the pressure falls enough for the compressor motor to run.

Running great but shut down mid ride. Acted Like the kill switch was hit. Checked the switch it was fine. Started right back up. Ran for another minute then shut down again. Plugs have spark, fuel...


My guess is that this is not a car or truck, but rather a 4 wheeler. It may have a low oil shutoff, or bad coil that fails as it gets hot, but hen cools a bit and seems fine. Check for spark immediately as it fails.

Bosch Axxis WTE86300US turns itself off after ten minutes, won't turn back on for a few minutes after that


I would bet you have a bad sensor. There are a couple of sensors that monitor heat. When it gets too hot they shut it down as a safety precaution. Once it is cool enough it will start up again.

It is a Bryant Legacy AC unit. Model #123RNA060-B. It has been running fine, now it has suddenly shut down. The interior fan is working, but the fan at the compressor shuts down. It will work fine for...


I had a unit do the same thing to me, everytime I would leave, it would stop working again. I had a bad fan motor that would spin fine and work for a little while, but would shut down. It was the motor windings that would overheat and shut off, as soon as they cooled, it would start back up. One way to check is to feel the top of the unit where the base of the fan mounts and see how hot it is, best to check while it's not working how it should, but try not to run it very long or you could damage the compressor. Hope this helps!

The a/c unit cooling fan shuts down shortly after unit kicks on.


If a fan motor quits working during a cycle it usually means that the thermal protector is turning it off. If you had an amp meter on it, you would notice that it is exceeding the listing on the nameplate, Nine times out of ten this is irreversable, the motor needs to be changed. Sometimes if there are oil ports on the motor, you can add a few drops of zoom spout oil and that does the trick. But usually the motor is already damaged. Good luck.

Lennox Gas Furnace that turns on and shuts off in minutes


After troubleshooting like mad, I found that the flame sensor (rod that sits within the flame) was fouled with carbon on the surface. I believe this shields the rod from proper heat detection and the sensor reports that there is no flame and to shut off the gas valve to avoid explosion. Once I pulled out the rod and cleaned it with a wire brush, I have no problem whatsoever--fixed.
