Comfort zone infrared heater runs for a few minutes a then completely shuts off


if unit runs ok for 3 to five minutes then completely shuts all power lamps off , then its hi temp limit sensor (safety) has been tripped , this usually goes out due to failure of main temp control , in point of fact contacts in temp switch literally weld them self's together and cant separate to allow heater to control temp

Master 125,000 propane heater will ignite but when you release the button it cuts the gas off, takes about 5 minutes before it will stay on and you can change the setting. How can this be fixed?


? doesn't this control On/off on a thermostat ?? the button your referring to is it the piliot test button ? if so I guess you've found a loophole in there test strategy by holding it down for five minutes to get it too stay on ,
what does this heater do when it shuts off on seeing a heated water temp to setpoint (or doesn't it ?) as if the test button is the only way to light it , this button bypasses a few normal safety switches (allthogh I didn't know about the five minute thing) one of the most common safetys that goes on these heaters is the heat exchanger over temp switch , seems the wires get hot and the little connectors fall off it

Some yahoo turned my heat up locked my screen Lennox COSTATO2AT1L


Either shut off power at the furnace, or remove the T-stat batteries, and wait 10 or 15 minutes, and repower it back up.

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 lf24 garage heater, starts then shuts down.


Here is a link to the manual for your unit heater:

The 4 flashes is a high limit or roll out switch is open. There are 2 or 3 little brown or black button looking switches with a little button on the top and a wire attached to each side. Press the button on each, you may hear a slight "click". If you do, that is the one that was open. Hope this helps.

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.
