My heater turns on the gas starts but then it shuts down

My heater starts and fires up as normal in the past the blower would turn on about 15 seconds to 30 seconds.now the blower never turns on the unit shuts down and the digtial teromstatgoes blank.The blower works bacause it turns on with the centeral air.i replaced the blower about 2 months and the air worked great.im wondering if it is the termostat due to the fact that after the heaters fires up for a min it goes into a safe mode and shuts down but when you look at the theromstat up stairs it goes blank but when you move it to off and it cools down it starts to show the temp.

I have a Lennox Conservator III G16 and when I turn the termostat up to turn on the blower want come on, but on occassions my wife said that she tapped on the side of the furnance and the blower might start working. I vaccumed out both blower area and the upper furnance compartment, but still the blower want come on. Our dyer is located in the same room as the furnance, we had a HVAC associate check it out and he stated that we needed to vent our dyer outside to prevent dust buildup and a safety hazard. What do you think is wrong with our blower and we have not found a solution or method to vent our dyer outside as of yet.

Try to locate the red and white wires either behind your thermostat or on the furnace itself. Jump them out and see if the furnace stays on. If you do it at the furnace you will need to hold the door switch down. If it runs fine, you have found your problem (the thermostat) if it goes out again, the furnace will display a number of blinks on the circuit board. Look on the reverse side of the furnace access door and there should be an Error Code chart to get you started figuring where to look next.

You have a dirty or bad heat sensor. When you remove the front panel on you furnace you will see a probe that is 2 or 3 inches long that is in the flame when the furnace fires up. If it doesn't detect a certain temperature within the first 30 or 40 seconds it shuts down the furnace. You can either clean the probe off with sandpaper, or purchase a new one. They aren't very expensive and are easy to replace. In my experience it is usually a build up of carbon on the sensor and a good cleaning with sandpaper and alcohol usually takes care of the problem.

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.

Williams Heater console floor unit


Is this a floor furnace? If so sounds like the switch for the blower, which is mounted on the side of the fire box is bad. There should be 2 of them, 1 for the blower to start 1 for the blower to stop when the fire box is cooled down. It wouldn't hurt to just replace both of them.

Heater Burner ignites but main blower motor will not turn on.


it sound like the blower motor may be seizing up. try spining the blade by hand to see if it feels free or not. the motor could be trying to turn but can then tripping itself out on overload. (most motors have built in safety overloads which will trip during an overcurrant event. aka too many amps.) you may have to replace blower motor

Blower works but no heat


If in fact you have the above listed furnace, you do not have a pilot but electronic ignition. You will need to remove the front cover on the furnace, tape down the door safety switch and then have someone help you by turning up your thermostat to a very high setting. Watch and listen inside the furnace. There should be some blinking going on at the control board followed by a small blower fan starting up. Then after 10-15 seconds there should be a click followed by an orange glow viewed thru the viewing window to the burner section. In a few seconds the gas valve should click and the burners will ignite. There is a safety switch that will sense flame and then keep the gas going to the burners. If it does not sense it, it will shut it off within 10 seconds. If all is well so far, your blower will turn on in about 90 seconds after flame. There is a diagnostic code chart on the back side of the access door if you get an error code (blinking) on the control board.

Always check little things like air filter, condensate drain and broken or loose wires.
