No need to clean the ignitor, it is a HSI it is ceramic and really easy to break. You should not remove it unless it is already broken. Yes, you should clean the flame sensor.
Absolutely! Last year the float switch on my sump pump went. That switch isn't available locally so I ordered it. Thankfully I was able to coax the original worn-out switch to work just long enough until the new one arrived! I was inches away from a basement flood situation. All due to a $15 switch! Excellent advice. Thank you billnipp2309....🙂
Sand paper will make grooves in the flame sensor that will cause it to give you hassle. Better to use a dollar bill or scotch Brite pad to clean sensor
The easiest way to tell why your furnace is not working is to look at the lights on the motherboard and see what they are doing and then look at the inside of the cover and see what the troubleshooting guide says.
Yes, agreed. I've seen the chart on how many LED flashes, what sequence and what different flash patterns mean. Quick way to pinpoint an issue. Thanks for the feedback!
