Expert:  Appliance Tech Larry replied 7 years ago.
did you replace the small themostat on the mag tube
Customer: replied 7 years ago.
No. We used the old one.
Expert:  Appliance Tech Larry replied 7 years ago.
you can jump the themostat and try the unit and if it heats then replace it and there are a couple more inside too you can do this to one at a time to see which is the problem / thanks

Where are these thermostats. and how many are there?

I've read that it can also be a diode or a large metal can capacitor. Could these cause it not to heat also?

Expert:  Appliance Tech Larry replied 7 years ago.
the thermostats are number 1249 and 1430 in this picture and the diode is number 1439 and the capacitor is 1438 ,,, i would check the themostats and it they are ok then i would replace the capacitor and diode

We will try these things tomorrow and if we still have a problem how do we get in touch with you again?

With the age of the micro do you think this is worthwhile to try to fix? Thanks

Expert:  Appliance Tech Larry replied 7 years ago.
for these parts i say yes but if it gets into the hi-voltage transformer then no ,,, even after you hit accept you can come back and pick up where we left off and i will be here to help / thanks
