Question and Answers

Q:

I purchased a replacement control board for my GE Microwave. After installing it, the microwave goes on as soon as power is restored. And even with open door. JVM1850SM4SS

A:

Thank you for being Sears’ valued member and for contacting SearsPartsDirect.com with your question about your microwave. I am so sorry replacing the control board resulted in the microwave turning on when the power is restored. I know what a time saver the microwave is and I am sure you want this issue fixed quickly.  In this case I recommend you have the microwave serviced by a qualified technician. 
 
We do not give diagnostic or repair information on microwave ovens because they are inherently dangerous to service. Microwaves contain high voltage internal components that can retain a lethal electrical charge even when the microwave is unplugged from the power supply. Special equipment is needed to work on a microwave starting with an anti-static wrist strap grounded to the microwave to even test components in it. Even minor door repairs and adjustments can cause microwave leakage, and a microwave shielding leakage test MUST be performed using a survey meter after ANY/ALL microwave service. 
 
For these safety reasons I strongly recommend having this repair completed by a qualified service technician. You can schedule service online at www.SearsHomeServices.com or by calling 1-800-4-MY-HOME (1-800-469-4663). Here at SearsPartsDirect.com we love to help you with your repairs, but our expert advice is that microwaves are just too dangerous for a do-it-yourself project. 
 
Thank you for your understanding in this matter and I hope we can help you with any other questions and repairs in the future. Thank you for choosing Sears.

GE JVM1850SM4SS microwave Ge Microwave

A:

Thank you for contacting SearsPartsDirect.com with your questions about your Microwave. I am so sorry to hear that the microwave has stopped working. I know what a time saver the microwave can be and how inconvenient it is when it isn't working. 
 
I can appreciate wanting to diagnose and repair the microwave yourself, however I strongly recommend against it. We do not give repair information on microwave ovens because they are inherently dangerous to service. Microwaves contain high voltage internal components that can retain a lethal electrical charge even when the microwave is completely unplugged. You need special equipment to work on a microwave starting with an anti-static wrist strap grounded to the microwave to even test components in it. Even minor door repairs and adjustments can cause microwave leakage, and a microwave shielding leakage test MUST be performed using a survey meter after any microwave service.

Q:

GR Microwave

A:

Microwaves contain high-voltage components that can retain a lethal electrical charge of up to 2200 VAC -- even when the microwave is unplugged. Repairs and adjustments, even minor ones such as , can cause microwave leakage. A microwave shielding leakage test should be performed after any microwave service. It is for these safety reasons that we are unable to guide you in microwave repairs and instead recommend scheduling service with a qualified service technician. You can schedule service online with Sears Home Services or by calling 1-800-4-MY-HOME. We thank you for your understanding in this matter and hope we can help you with other questions and repairs in the future. Below is a link to get up service.

I am not scheduling service for this work. That is unnecessary and would be more expensive than buying a new unit.

Here is a direct link for the installation guide on that microwave: Installation Instructions for GE Microwave Model JVM1850SM4SS . The installation guide shows how to adjust that fan to recirc the air back into the kitchen.

That clip on the vent grill that you are describing appears to be part of the vent grille assembly (part WB07X11019 or part WB07X11175 for the entire vent assembly). Those are expensive parts. Here is a link for the vent grille: Grille Part WB07X11019 for GE Microwave Model JVM1850SM4SS . Here is a link for the entire vent assembly: Grille Assembly Part WB07X11175 for GE Microwave Model JVM1850SM4SS . Replacing that component will cost more than $100 unless you can find a used part through a websearch. There is chance that you can repair the broken clip using super glue depending on the nature of the break.

I hope that this information helps. If you need more assistance, let us know.

NOTE: Adjusting the fan according to the guidelines in the installation instructions and fixing that clip on the vent grille should not expose you to any shielding issues or high voltage. Any repair of internal components would be dangerous as described by Marc H. in the above response. I do not recommend that you remove the cabinet or access any internal components beyond what is described in the installation guide and owner's manual.

Great Lyle. That is exactly the kind of information I was searching for! The installation manual especially. I wanted to verify I rotated the fan correctly and there wasn't anything else I missed. I'm good now. I also thought about super glue (or gorilla glue) on the grille since only one side is broke. The replacement cost on that seems rediculously high compared to buying a new unit. I don't know how this place broke since it's a relatively new microwave. Anyway, that is exactly the information I wanted. I understand the safety disclaimer but I don't intend to open it or access any internal components. THANKS SO MUCH FOR YOUR HELP!!

Thanks Chris. I understand your concern about the cost of those GE replacement parts. Hopefully you can repair that clip instead of replacing that component. That should not affect the performance of the microwave. I am glad that you understand the purpose of the safety disclaimer. Let us know if you ever need more help. You will normally receive an initial response that will often help you with the problem that you are describing. That initial response is normally followed by a more detailed reply from a technician (hopefully within 24 to 48 hours). Sometimes it takes us a little longer to respond with detailed technical advice.
