So dear wife called me at work Wednesday to decry that the oven would not come on and she had a roasting pan full of pork chops all breaded and spiced ready to go.
I came home early, popped a big cast iron pot on the stove top, added a bit of shortening to be sure it was seasoned and half an inch of water and loaded the pork chops in. Top fits well, so sort of a steam bath.
Every few minutes I rotated the bottom one to the top.
Then left on low for 15 minutes so to be sure all was cooked through, Pork came out nice and moist and tasty. Will definitely try cooking that way again.
Then after dinner dishes away and left overs stored, look to the oven.
Based on my history with gas appliances, having fixed the bbq, clothes dryer, and furnace over the years, I went to the ignitor first. It measured about 260 ohms cold, so maybe a bit high but not open. Loose terminal on the gas solenoid lead so I crimp that a bit tighter. Solenoid measures a few ohms, seems right. Try firing it. Still a no go. So no smoking gun so far.
So I get voltmeter leads hooked up to look at power in the plug at the bottom inside of the oven that powers the circuit. Weirdly fluctuating values, never over 30v, and I was expecting 120V when I set the controller to turn the oven on.
So I had been up since 4:30am that morning, with a proposal to write at work on my mind. So logic was thin for me by 7:50pm. So sleep on the problem.
Next morning I peel the oven controller out so could probe the control signal, right where it leaves the controller.
Same wonky voltage.
Pry the control pc board gently out of its holding housing to look at the foil side.
Aha.
Modest black burn marks showing a bad solder pin to foil joint on the relay load terminal.
Out to the solder station setup in my shed.
Add extra rosin to clean the joint then resolder it.
Reassemble and bingo, back in business.
Much nicer than the $300 cost of the replacement part I had researched the night before
