790.75903993

 

Thought I had a bad broil ignitor

 

Hooked up a new broil ignitor, it took a long time to start glowing.

 

I unplugged the ignitor and and checked for voltage, I was getting 120v.

 

Reconnected ignitor, checked voltage at rear of ignitor plug and was getting 66v.

 

Is this a computer problem?

 

Is it losing voltage somehow when a load is hooked up??

 

I've never seen this before.

 

Thanks!!

Oh yea, bake works fine, strictly broil, I'm guessing the computer is losing voltage somewhere when a load is hooked up, the relay??

 

So how would that happen?  Is the contact just bad and not sending enough voltage??

yes, would seem to be ..
Relay K2
also check the Gas Safety Valve
should be no more than 3v across each coil
OR about 1 OHM across each coil

Might just be bad solder connections on the relay legs on the board.   I find this alot it seems on Frigidaire range boards.

Thanks budget, i know some people might solder back together, but i dont like messing with them, and the customer doesnt want to shell $300 for the computer.
