    Hey guys my oven is not heating. I found the thermocouple was bad i just replaced that.. But i also noticed when i turn the oven on. It reads 345* But of course it doesn’t heat. I also do not have 24v to my SSR. Any other suggestions would be great.

    If it reads 345°, I take it that’s the setpoint?

    So, from looking at the schematic, you said the SSR isn’t getting 24v. Make sure your meter is set to read DC voltage – NOT AC. I know the troubleshooting chart in the manual says to check for 24VAC, but that’s gotta be a typo. The SSR is rated to operate from 3 – 32 VDC.

    BTW: Don’t be doing any voltage readings from ground. That will get you nowhere.

    Also make sure to be checking for that same output from across the control board’s terminals J3-1 and J3-2.

    Here’s the manual:

    Is the polarity correct on the thermocouple?

    I got to work on it today.. The mainboard is bad. I took a board from my good oven and it worked just fine.. Other than the cooldown timer not working. And than the SSR started smoking.

    So it’s going to become a parts oven. It also needs a touch membrane that cable broke. (or i’ll repair it).

      Are the two voltage setting correct for your imput power? Both the control board and low voltage tranformers have mutiple taps.

    ya everything is correct.. it was the board.. getting nothing from J1 and J2. I think it fried when i tested it on a generator that was pushing way to many volts

      That would probably do it, boards don’t like wrong voltages very much.

      How much was the board?
