The ignitor glows very bright and occasionally it does ignite. The flame sensor I took snadpaper to, and made sure it was clean. The three flashes say that the pressure switch is stuck open. Are there some readings I should take off the ignitor and sensor? Are there additional radings I should check...

Well I got the new valve today, and just put it in, only to find the same problem- gas valve clicks, I get ignition, and as soon as the blower came on, it went out. Second time it tried, the gv just clicked and then I got three blinking lights. Third time, same thing, Gv clicked and then I got three...

Checked the voltage across those two wires at lunchtime, I let it call for heat three times and I always recieved a 24Vac reading across the yellow and black wires. I have ordered a new Gv and I will see if this fixes the problem-fingers crossed. I will try to let you know the result after getting t...

What am I suppose to read when I test across them when it calls for heat? Should I read 24Vac across them when it calls for heat? If it does read 24Vac across them when it calls for heat, is it more likely that the GV is bad versus the board? I also noticed that it will not hold the 24Vac when it ca...

I checked all tubes, and the induction motor comes on just fine - I just replaced the capacitor for that, it went out. What doesn't make sense to me, is that when I hook up the yellow wire to the GV and leave the black wire off, I can read 24Vac across the Gv contacts, but when I hook the black wire...

The light blinks twice sometimes, and sometimes it blinks three times - both pressure related. When I disconnect the two wires and check the yellow to chassis, I get 15Vac initially, and 24-26Vac when it is tripped on, the black reads 0Vac from the black to chassis.

Nordyne Gibson KG6RC-100C-16B I have just installed a pressure switch that I just ordered from you, and now realize that this is not the problem. I have checked all of the safety switches and all seem to be getting 24-26VAC to both sides of them. Now here is where I am stumped; there are two wires t...
