It's Dead Jim!

Kenmore (think it’s a Whirlpool if I looked up the 665 right) microwave and hood combo.

Just went dead. No lights no nuthing.
Checked socket - it’s live.

Am aware there are thermal fuses and maybe a circuit breaker inside - but are they relatively easy for me to locate and check?

Reasonable skills - don’t mind dissasembly.
Have a decent multimeter as well.

Thanks!
