They can't figure out why the sensor keeps popping. Also the day they replaced the sensor the thermostat wouldn't get the house above 68 degrees unless I removed the panel on the unit containing the control board, like cool air needed to get in. Replaced the fan recently to and it seems to work. Any ideas?

Your furnace tries this ignition sequence again, and the same thing happens. After 3 times the furnace goes into lock out, and the only way to get it out of lock out is to turn the power switch off and on. Everything starts over again without ignition of your gas burners. Solution: First, turn off the power to your furnace. Next, remove the screw or screws that hold your flame sensor in. Please do not confuse the flame sensor with an Ignitor. We do not want to touch the ignitor at all. If you touch an ignitor it will shorten the life of the ignitor or it will break. Clean your flame sensor with light sand paper, steel wool or emery cloth. You might need a new flame sensor, but most of the time they can be cleaned and your furnace will work well after cleaning. Most of the time when they go out the white porcelain is cracked. You might want to have a spare flame sensor on hand.
