No gleaming? No fire? Your hot surface ignitor is awful. Essentially that will be the case more often than not.

Questions and Answers

Question:

Remarks
Emily on December 08, 2019:

So is my ignitor awful assuming I need to fan it on its subsequent light? I previously cleared the sensor off and it appeared to work for some time however at that point it stops. I don’t know whether how I am phrasing this seems OK yet I would rather not buy some unacceptable part. The odd thing is it appears to work in some cases subsequent to turning the switch on and off multiple times.

Michael Langan on November 12, 2019:

with an igniter with an intensity sensor, does the intensity sensor fill a similar need as a fire sensor? I can’t track down a fire sensor on my unit, yet it is acting as if a fire sensor issue exists.

Brian on October 12, 2019:

So my ignitor is becoming red yet the gas won’t open and burst into flames. The LED indicative says “inappropriate fundamental ground or line voltage under 75 volts. Or on the other hand, broken ignitor or open ignitor circuit.” Should I supplant the ignitor?

Dan Reed (creator) on February 26, 2018:

Be certain the igniter you’re utilizing is the appropriate voltage…typically 120V or 80V and furthermore that the power being provided by the board is legitimate. If not, it very well may be causing the issue.

Richard M Cortellini on February 25, 2018:

since supplanting the last ignitor 2.5 a long time back, I’ve supplanted the ignitor 2x over the most recent fourteen days.

Dan Reed (creator) on December 30, 2017:

California – I’m inclining towards as far as possible/fan switch or one of the carry-out switches. It’s certain to behave like a fire sensor however that precluded this future, my suspects. They are somewhat reasonable parts. I trust it is as those are simple fixes yet difficult for me to make certain from here.
