Your unit is short cycling. Most likely suspect is the thermostat is mounted in direct line with the discharge air. Adjust diffuser away from stat or relocate stat.

Hello, sounds like the limit switch is opening on the furnace.Usually when a furnace goes off on its high limit is becuase the airflow is being restricted making the furnace overheat. a limit switch is there to protect the furnaace from overheating, most cuases are either dirt or the blower motor not running up to speed, anything that cuts down on the airflow will cause the high limt switch to open.

It may be your thermostat, but try this first to see if time delay relay may be sticking. When it won't shut off, turn propane off, and go outside and unscrew the 2 screws that hold your cover on, and lower the cover down. Look straight ahead, attached to the housing of the fan up near top you'll see a square relay (time delay relay) with 4 male spade connectors, and wires attached to each. It's usually held on with 2 Philips screws. Give it a little rap with the handle of a screwdriver or similar a couple of times, and see if fan stops running. While your there as well, pull the wiring connector off the ignition board, and put back on a couple of times, to clean the connections. Now try it again, and let me know what happens.

Flame sensor dirty


Sandpaper lightly scrubbed over the sensor tip to remove any contamination.

Sometimes cleaning is not enough and the sensor must be replaced.

The unit will turn on and run fine for a few minutes then shut off. It won't immediately turn back on, almost as if it hans to cool back down first. Any ideas i have a lennox furnace


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.

Lennox furnace 17 yeanrs old. flame comes on and the shuts down sometimes right away some times in a few minutes. We have the furnace go down to 58 at night. It takes all day to get back to 67.


Sounds like a dirty flame sensor.
Also 9 degrees is a large swing to recover. Most specialist will advise no more than a 5 degree set back, otherwise recovery time eliminates any savings you may achieve.

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.
