How do I troubleshoot this?  I have a tester but not sure how to use it.

Step 1: Remove power.

Step 2: Remove top grill.

Step 3: Open control panel.

Step 4: Retrieve tech sheet/wiring diagram from inside control compartment.

Step 5: Post a copy of your wiring diagram here or fax to me at 866-315-4504.

You know I forgot, the diagrams are posted here:

http://applianceguru...m1/20490-2.html

on the second page--I originally had had a problem with the oven (its an oven/micro combo) not working and narrowed it down to the Electronic Control Panel for the Oven--replaced that and now the oven works fine but the MW fan will not turn off--that problem by the way started AFTER the first problem but BEFORE I replaced the ECP so my guess is maybe something shorted while I was troubleshooting the other problem.

The good news is the MW and the oven work fine--just that the fan does not turn off on the MW--this is the fan that runs when you turn the MWn and then goes off when you turn the MW off or it finishes its cooking cycle.

I will also fax tonight or if you give me an e-mail I can e-mail a much better copy of those diagrams because I had to shrink them down to the 200K limit for the forum.

How do I check that?  I have a Multimeter, I am just not always sure how to test--i.e., whether I am checking for continuity or Ohms and how specifically to do it.

with power disconnected and Fan Thermal T.C.O. (Thermodisc) disconnected,

check continuity (it's a switch .. either open or closed)

What does it look like?  Can't find a picture of that part number.

E-mailed you the drawings by the way!

Excuse my ignorance on this but not sure what that means?  Do I set the Multimeter to the Volts side or the Ohms side?  What setting (i.e. 2, 20, 200, etc?)  (See  multimeter below).  Then--what am I looking for? 0 or some other number?

200 OHMS
or the setting just under that
(will "beep" if continuity)

shouldn't "beep" nor have continuity at room temeperature
should read "infinite" OHMS

thanks for the emails ..

I already had 31-9098, but it didn't show the Microwave portion ..

it does refer to 31-9084 for the M/W portion, which I will PM the link to you ..
see page 37 (PDF page 39)

Ok, we figured out it was a sensor that was bad (see below) but I can find it in the product list.  Its a normally open sensor rated at 60 C.  Can anyone link me to that sensor?
