Hi. Welcome to JustAnswer. If the answer I provide for you is helpful, please click 'ACCEPT'. I won't be paid if you don't. Thank you.
What you will need to do is see if you can pull the error codes from the units memory. Please see the screen shot from the service manual below for the procedure.
If the unit will not go into the diagnostics mode then you have a failed control board. Please let me know what you come up with and we can go from there.
Your screen may indicate that I have stepped out of the chat. Please do not be alarmed. I will recieve a notice at the top of my screen when you have replied.Thank you.
I performed the diagnostic test for the machine by pressing the start and pause cancel buttons simultaneously and got a readout that said E41
Ok one moment please.
Ok looks like a door lock indicator switch (PTC) has failed. Please stand by and I will upload a service manual for you to work from.
Please click here to download the manual. Go to page 64 and perform test #9. The information to access the door lock is on page 69 of the manual.
If the unit failes the test then replace the door lock. Parts should be available locally or via the internet at http://appliancezone.com There is a chat feature at the top left of the screen. Just provide the operator with your model number and they will be happy to look up the part for you.
How do I measure the resistance of the PTC?
You will need a volt ohm meter to do that. You can get one at Home Depot for about 10 - 15 bucks, or maybe borrow one from a neighbor.

How do I measure the resitance of the PTC?
Thanks I will try this.
Do you know how to use a volt ohm meter?
If you have a friend or neighbor that has a volt ohm meter just ask them to do the test for you. It is a simple continuity test. Once you see how it is done Im sure you will be able to do the test yourself.
I am having trouble removing the bellows from the front panel. Any suggestions?
did you get the retaining spring out?
no where is that located?
Do you have the manual I sent you?
yes. I just printed out page 64 and 69 but can easily refer to other pages. I will take a look
Page 69 has a picture at the bottom showing how to remove the spring from the boot.
Sometimes printers do not print out pages as indicated on the page numbers. Please look at the manual on your computer screen.
Printers will count the cover page as page one.
just tested the PTC and it read 2 on the OHM meter
Sorry for the delay replying. I was busy with another customer.
The PTC should have an ohms value in the 1000 range. Please make sure that you have the ohms meter set to a range that will display more than just one number when you do the test.
my ohms meter is an analog meter with a needle that goes from 0 to 200. Is it possible that those are thousands?
Is the needle just below the 2?
No just over
excuse me just below
Ok if it is reading below the 2 then it indicates a problem with the main control board ("Reads around 1500 Ohms. Defective control board"). Please see test #9 on page 64 for this information.
Would you like a link to purchase the new board on line?
what do I do about a defective control board?
yes please. Do you have any idea how much they cost and can I install it myself?
The manual has the repair information in it. One moment please and I will get you the price and ordering information
Please click here to order the new control board. $137.00 plus S&H
Ok I'll be on line most of the morning today.
Ok lets back up to the beginning. Run the on board diagnostics again and see if you still get the same error codes.
Hmmmmm. It has to be the PTC then. What I cant figure out is why you are getting a good reading from it. Are you testing it with the wires connected? If so please unhook them and see if you get an open or shorted reading from the PTC.
Your meter will read zero in either case.
I'm going to have a fellow expert review this question and see if he may have any input. He is presently working but is on line between customers. It may take a while before he gets back to me.
Ok I'll let you know ASAP what they say.
Just make sure that the magnet is still in place. The reed switch can be tested by doing a continuity test with your multimeter. It should read zero both with the drawer open and closed.
FYI: Both of the other experts that I had review the question thread agree that if the magnet and reed switch are working properly that the door lock is bad even though it reads good.
Ok I will be sure to check back after I finish work today. Not sure exactly when I will be done. Probably around 4 - 5pm PST.
Absolutly, yes. Only older models had the reed switch. If yours does not have one then replace the door lock.
