I am working on a 1993 Janitriol model number GMPN100-4. Actually two
of them in the same residence. Big ranch house with on on each side.
I watch the Ignitor turn on, the main valve opens, it ignites and stays
lit for about 5 seconds, then the flame goes out. It waits about 30
seconds then does the same thing again.
It stops after three tries and then I get a single blink from the
At least I think it is a single blink. It blinks on, waits 1/2 a
second then blinks once again, repeat.....
I replaced the flame sensor and it still does the same thing.
Reading the sticker in the furnce, a single blink means Gas flow, Gas
pressure, Gas valve, or Flame sensor.
Sure seems like it is the flame sensor to me, but I have swapped it out
It wouldnt flame on if it was the Gas flow, Gas pressure or Gas valve
Thanks in advance..
