Thermador S302TB oven problems

4 posts in this topic

Problem started with erractic operation of top broiler element--sometimes comes on, sometimes not. Pretty busy with other stuff, don't use the broiler a lot, so have been ignoring. This week, a couple of cycles where the oven bake element heats weakly or not at all. OK, time to check it out. Results:

- Bake element continuity good--terminal-to-terminal and exterior to ground.

- Voltage to element starts at 9.5v, you can hear it click, then 85v. Goes back and forth, no heat. One cycle out of 15 did fine at 240v and heated up like normal.

Haven't pulled the broiler element yet, but it looks perfect.

Don't have the service manual or schematic (requested on the other forum section) so I don't want to start pulling it out of the wall until I know where I'm going.

Seeking wisdom.

Domo,

Tim

You'll need to apply this kata for toubleshooting electric ovens so you can isolate which part of the circuit is falling down on the job:

I think you'll find that you'll need to replace the range control board:

That was what i was guessing--thanks. Do you know if the control board is accessable from behind the top panel or am I going to have to pull this baby out of the wall?

I PMed you the training manual which has some disassembly help and the kit comes with instructions.
