Hotpoint JE740WY/GY Microwave Oven - Answered Questions & Fixed issues

The pads actually share some of the same lines inside the touch pad. There are silver oxide traces inside there. If a trace inside breaks, it depends on which trace breaks as to what pads dont work. If a trace that is common to say pads 1,3,5,7 you would lose function of those pads. 1.....2.....3.....4......5....... it is sort of set up like that inside wher eone connects to another and so on. So lets say a line between 2 and 3 breaks then you would lose pads 3, 4, 5 and any others on that same line. Will have to replace touch pad, cannot repair.

The Hotpoint RVM58003 (circa 1984) cannot be lifted off a hanger after the four top screws are removed because it doesn't have a separate pre-installed hanger like newer units do. The rear mounting screw holes are part of the outer frame of the unit, which requires removal of the Microwave sub-assembly of the Hotpoint RVM58003 to expose the outer metal frame and the array of pre-drilled rear mounting holes before the rear mounting screw(s) can be accessed and removed. Based on my recent experience removing a Hotpoint RVM58003 Microwave Hood from 1984 it appears the unit was originally installed this way too. Please note that this is a very involved process. Basic steps are: 1) Unplug AC power to the unit, or turn off the circuit breaker. 2) Remove the top plastic grill over the door and control panel (2 screws). 3) Next to the grill screws remove the larger left/right screws holding the Microwave sub-assembly in. 4) Drop down the hinged light bulb/air filter cover panel (mine had 7 screws). 5) Remove the small metal cover plate on the right under the control panel. This exposes the Microwave sub-assembly electrical connector. 6) Disconnect the Microwave sub- assembly connector. 7) Carefully pull the Microwave sub-assembly out of the frame and set aside. You may need to fish the power cord through the cabinet or unscrew the power cord terminals. NOTE: this is best done with a helper because this sub-assembly is about 25-30 pounds. 8) Once the sub-assembly is out the rear plate is exposed and the rear mounting screws can be removed. I found that the GE/Hotpoint Owner's Manual does not have installation instructions. Neither does the GE web site, they only have the Owner's Manual. For more specific help and instructions I suggest calling The GE Answer Center at 800-626-2000 or hiring a professional installer experienced with this older style Microwave Hood.

it could be the cap, or diode or mag tube or transformer

Then chances are it can be repaired without having to buy a new board. I would suspect a connection or power component on the control board.

google your Hotpoint model number include parts, Dowsil is approved but is price prohibitive.

Could be a faulty control knob.

Yes you do indeed need a new door. The door is a complete safety unit and access to the microwave.

There is a chip that controls TOTAL operation of the microwave, sounds like it malfunctioned. It actually sound like the entire board has malfunctioned. good luck https://www.6ya.com/mrmmike

Many microwaves have similar issues. Usually, (not always) only the light is on and the fan is running, not the section that produces the microwaves. This problem can be caused by the door switches that are out of alignment or a defective control board.

Most microwave diodes will work just fine from system to system. The most common ones I use are rated at 550ma. When you check your old diode what made you think it was bad? They are such a high rating you will not get a reading on it with a regular ohm meter. Mostly on HV rectifiers if it is not shorted ( Zero Ohms) it is probably good. If you have no high voltage then substitute it and see if you do get high voltage, then you know it was open. Follow the video and give it a try.

"F3" means you have a shorting membrane keypad. I regularly repair these controllers and details are here. If you have other questions, it's best to follow up with me directly.

None to my knowledge, but common faults include keypad failure (may show error code "F3") and cooktop light failure, both of which can be affordably repaired. (See link below) For more free DIY and other help & advice, feel free to contact me via my site below. Please include FULL model number*, FCC ID number*, + detailed symptom information.

JX-81J is the microwave recirculating charcoal filter for several models of GE and Hotpoint microwaves. The installation instructions will be available from the manufacturer with the model number of the microwave itself. One microwave that uses this filter is the RVM1535MMSA . See http://products.geappliances.com/ApplProducts/Dispatcher?REQUEST=HPSPECPAGE&Sku=RVM1535MMSA#tab1_ for all of the details on this microwave. The owner's manual, http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=39-40541-1.pdf , shows the installation of the filter on page 34. The guide for installing the microwave above the range is http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=39-40425.pdf . If you have a different microwave, add a comment with that model number. I hope this helps. Cindy Wells

It may be a bad connection on the fuse holder, an intermittent fuse, a bad connection on one of the thermostats or elsewhere, or a bad connection on the control circuit board. If you want to contact me privately with the model number, I can give you or a friend free DIY troubleshooting help and I also do microwave control circuit board repairs. For more free DIY and other help and advice, feel free to contact me via my site. Always include your FULL model number*, FCC ID number*, and detailed symptom information. * from the tag in the cooking cavity or elsewhere on the oven (or send a clear photo of tag) William E.

Have you tired unplugging the oven for 5 minutes (must be cool if you did a cleaning) and see if it will reset the system and unlock it.

The control buttons are likely defective. Is the MW working?

Can the safety switch is faulty. Try to repair it with a technician before use. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
