Flame sensor is part of the igniter and may need to be cleaned up. To much build up will cause this issue.

turn on the power to the furnace, turn on the gas valve light the pilot light some haveor had on the gas valve a push button when trying to light it you must press the button and hold it for a minute until the thermocouple warms up then let go of the button and turn the gas valve all the way on. Next is to turn up the thermostat and enjoy the warmth.

First, check whether the Ignitor is igniting the Heater, If the Ignitor is not letting the spark it would be the problem with the Ignitor, check for the cracks in the ignitor..

For changing the Ignitot follow these steps,

You can buy only the ignitor which is a small part, try soldering it into it by removing the old ignitor, Its Easy shmeasy job. Any one can do it. Otherwise you're looking at a few hundred bucks vs $20-30 at the most....

Sometime if you're fortunate, you may only need to sand the carbon off the ignitor if no crack found in the ignitor!

Please revert me, if you need more assistance, i would be very glad to assist you more.
If you were satisfied with the solution please rate this sollution.

Hi sounds as though you have a dirty flame sensor that you need to clean. On a propane unit, they tend to carbon up much faster then a natural gas unit. The flame sensor is located next to the pilot, and has a metal tip that rests in the pilot flame. Most are made of porcelin and will have a electrical wire coming out of the back that is connected to the module or circuit board, which ever you have. When they get dirty, they cant get hot enough to produce enough milivolts to tell the ignitor module that the pilot flame is established, and will shut the unit off. This will happen about 3 times until it is locked out. Just use a piece of fine steel wool or sanding cloth to clean the tip, and this should take care of your problem. If the problem continues, please let me know, and we can check further into it. You may have a ignitor module that you are loosing, or ignitor board. Please keep me posted on this, as I am sure cleaning the tip will solve this problem. Please rate me! 4 thumbs up would be great!
