It sounds like he incorrectly installed the igniter and it may be a huge danger to your home. A incorrectly installed igniter can cause a excess build up of gas and blow back flame or worst blow up your house. Only have a licensed heating and cooling contractor work on your furnace and not a handy man.

SOURCE: Flame Adjustment

Make sure the unit is operating on the correct gas, Natural or Propane (LP). The sound you are experiencing is either not enough gas and the flame is burning inside the burner port(s) or too much gas and the flame is much larger than it has to be. At any rate, get a technician to check the gas pressure entering into the home. NOW!

SOURCE: No heat, trouble shooting light has continious flash.

There is a vacuum sensor on most units tied from the exhaust gas fan to the sensor. Does the unit try to start? If the unit's exhaust fails to pull the switch it will turn off after about 30-45 sec after starting. "IT" thinks it's not exhausting and stops to keep from overheating. Do you have this exhaust fan and rubber hose to sensor? Can you see if that fan is turning on start?

SOURCE: Goodman furnace burner ignites then shuts off in about 10 seconds

if you have replaced the flame sensor and it will not stay lit, the draft safety switch may be opening. It works on positive and negative pressure created by the inducer fan motor.You may have a restriction in your heat exchanger or if is a high efficiency furnace, it may not have the drain tube installed properly with a trap. The trap works just like the trap under your sink and if water isnt in the trap, the pressures can be effected enough to open the draft switch(some call it an air pressure switch)

SOURCE: Main blower fan is not starting on my York Diamond

Hi,
Check to see if the blower motor is actually getting power to it...You will have to check for power on the heating speed terminal... and the neutral wires....you should have 120v across those two wires....
If you have power then the motor is bad...if no power then the heating relay went bad on the circuit board and you will have to replace the circuit board...

That is a common problem as those relays are often to light and wear out...

Just realize that without an electrical meter to trace things through you are really just grabbing at possibilities and not really able to correctly diagnose your problem...

Weather king select furnace


At the opposite side of the burners from the igniter there is a small metal probe/rod situated where the flame would blow across it during operation. This rod is for flame verification so the gas valve will know that the gas is being ignited. Often that probe will get carbon built up on it which will cause the furnace to light but then abruptly shut off because "the probe doesn't know there is a flame there". A fine grit sandpaper works well to restore it's conductive ability. However, if the furnace runs for a while before it shuts off you could very well have an obstruction in the vent pipe or an obstructed indoor coil. If cleaning the flamerod doesn't remedy the problem, I strongly recommend a qualified serviceperson look at it! The furnace could well be turning itself off because something is getting too hot and coming back on when it cools. Good luck.

The furnace control on a York furnace is locking out due to unable to ignite flame


possibilities are many, no spark due to ng ignitor, if draft induced , fan not coing on or has blocked flue, if unit is condensing type might have condensate in drian line, if standing pilot type thermo couple bad so not sensing pilot. so you see not enough info of what type unit you have to help narrow down possibilities

Janitrol furnace. burners ignite then shut off, blower runs but no heat


Sounds like a dirty flame sensor. On the opposite side of the Igniter will be a metal rod that is just above the burners, you need to remove this rod and clean it with a steel wool pad. Then reinstall it and turn Furnace back on. If this does not help let me know, it may also be a high limit switch tripping.

Janitrol GUPS075-3 Furnace burners will not stay lit


The first thing I would do is make sure the flame sensor is clean, this is a metal rod immersed in the burner flame on the opposite side of the igniter. If too much oxidation builds up on it, it will not allow the burner to stay lit. To clean, just turn off furnace and remove flame sensor and clean with steel wool and then reinstall. If this does not solve the problem there may be a problem with the gas valve.

The furnace will light up and the fan will blow but the flames cut out before my house reaches temp. i have the thermostat set at 70 and the house will not get above 55. i have tried turning the propane...


First, for those of you who might not know, "What is a flame sensor?" A flame sensor is a safety device. When your furnace's main burners ignite (light Up) the flame sensor picks up the heat from the furnace's main burning and says, "YES," and sends a signal back to the main furnace control board saying that it is OK to let the main burner stay on. Or if the main burners do not ignite, the flame sensor does not pick up the heat and says, "NO" to the main control board, Shut That Gas Valve and Main Burners Down! Thank God we have safety controls like the flame sensor. Most of the time, after turning your furnace's power off, you may clean the flame sensors with light sand cloth, emery cloth or steel wool. Reinstall the flame sensor and you are back in business! Over the years flame sensors can build up a light coating of burned-in dust and dirt. This insulates the flame sensor so that it doesn't sense the heat of the flame well enough, so by cleaning it you have almost restored it to its new condition. Seldom, but sometimes they do go out completely.

Gas furnace; flame will not stay on


Clean the flame sensor with a green scotch brite pad. Check all ground connections from the circuit board to the furnace cabinet. Check for a proper ground to the electrical box. Make sure polarity has not been reversed.

We have a Janitrol PGB 048125-1 unit and it is not blowing heat. the fan comes on when in fan only mode on thermostat but once we turn it to auto it goes off. we cannot get the unit to blow hot air. does...


If the unit is newer than 10 years I guess there will be no pilot light per sey. You will have to look at it to tell for sure. Here it is supposed to work. When there is a call for heat the thermostat will close and send a signal to the furnace to start the exhaust blower. When the blower gets up to speed, it closes a pressure switch that will send voltage to the gas valve and to the igniter. The igniter glows or sparks lighting the pilot. Once the pilot lights it sends a signal that all is well, then the gas valve opens up more and the burner(s) light. There is a sensor that tells the control board when the flame has stayed lit. Once that is done, after a period of time or as the heat exchanger gets to a specific temperature, it will turn on the room air blower and blow hot air. Once the thermostat has been satisfied, the furnace turns off. Now, get in front of the furnace and with the door panels off (you may need to tape down the door safety switch to make this work) watch the furnace go thru each step I described. Once you see where the problem is, you can start the proceed of repair. There may even be a flashing light indicating a problem. Find the wiring diagram on the furnace and look for a diagnostic chart and compare the number of blinks to this chart.
