Question about Microwave Ovens

Open Question

I have a HP 53132A which self-test Fails showing a ROM Failure. The manual just replaces the Main Mother board of the Counter. Is there any way to repair this board? Thanks

    I would post in the computer or printer section, as opposed to the microwave oven section.

    Or search via Google for your model and terms like

    board fix OR repair

    Good luck.

Reading F3 and workes by it self


MAKE THIS TEST AND FIX IT. God bless you
  1. Interlock switchIf your microwave is turning itself on, the first thing to check is the interlock switch. This is usually the first thing to malfunction that could cause this issue. If the interlock switch is bad then it will need to be replaced.
  2. Main control boardIf your microwave is turning itself on and the interlock switch is still working, the probable cause is the main control board. If the control board is defective it will need to be replaced.

Goldstar under counter microwave spindle won't turn


use the common sense, and logically, fix it. God bless you
Microwave Runs, Heats, but turntable does not move This is a fairly easy one. First, make sure the turntable coupler under the glass dish is not broken. Second, on the control board, find the turntable relay and test for voltage. Some turntable motors are 24 volts DC, so make sure your testing the correct voltage. If no voltage from the control board, then replace the control board. Otherwise head towards the turntable motor.
On OTR models, you can get to the motor by un-screwing the bottom panel on the microwave. On countertop models, there will either be a knockout or screw on access panel. Check for voltage at the motor. If no voltage, check the wiring back towards the control. If voltage, then replace the turntable motor. The component list below also shows how to test a turntable motor.

This oven is programmed with a self diagnostic failure code system which help for troubleshooting -H97 and as described above "mica piece and burnt smell" sound like Inverter Power Supply. DO NOT try to repair or re-adjust preset volume on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very high current Operating a misaligned inverter circuit is dangerous due to the Very HIGH voltage and current that is produced by this board.

Defective board must be replaced with new one -INVERTER POWER SUPPLY.

WHEN TRYING TO SELF CLEAN OUR KENMORE ELECTRIC RANGE WE GET THE E1-F5 LIGHT?


The E1 - F5 error code indicates that the oven door lock assembly is not operating. The oven will not begin the self clean cycle unless the oven door is properly locked. This failure is normally caused by a failed door lock assembly. In rare instances, it can be caused by a failed control board or a wiring failure. The normal troubleshooting for this problem is to unplug the range and check the wire harness connections between the control board and the door lock assembly. The first image below shows the access information for the components in this model of range. The second image shows the wiring diagram with the door lock circuit highlighted. If you are able to unplug the range and check the wiring connections, you can likely fix this problem yourself. If the wiring connections are okay, the next step in troubleshooting is to replace the door lock assembly (part W10107820). You can order this part from the Sears PartsDirect website. Replacing this part will likely fix your problem. If you replace the door lock assembly and still have the same problem then the electronic oven control board may also need to be replaced. If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

No power to microwave. I replaced the main fuse. it sparked and blew the new fuse. My meter shows a short (or at least continuity) from the appliance side of the fuse (removed) to the neutral (white) wire...


Look for the surge protector being short which is in the front end after the fuse. If so disconnect and check for the shorrt to change. repeat the same for the power supply to show a release of the short.
If the transformer, main capacitor is shorrt removve and check or replace.
Since the short is in the primary end you can get this sorted out easily as a short in the magnetron might not be worth.
So use the continutiy meter to disable one by one these compenents to confirm.

F-9 error on my LG lmvm1945t microwave


The F9 problem in this microwave is a bad magnetron or inverter.

From other users:

"F-9 on this microwave IS inverter related. My problem was the magnatron and checked out bad with the help of (the tech sheet). It would run for a few seconds making clicks and then say F-9. It has been working great since I replaced the magnatron."

"f9 Kenmore Elite 36 " over tne counter microwave is supplied by LG made by Gold Star, made in China. It's main problem is the high voltage inverter board supplyed by Sears Parts. If you get a F-9 code on your microwave display screen2.gif and the micro quits it's probably this board. Reset the machine by pulling the power plug and waiting an hour. If it is the high voltage board is at fault it will probably fail after 45 seconds of start up. This part is really hard to get at but is less than $100. A qualified technician should be able to remove and repair this item in less than hour. Some techs will quote you $300 labor, don't buy it, it should cost a $100 or less. No need to buy another microwave."

The first thing I would suggest is a hard reset. Unplug the unit for several minutes or so. Then plug it back in, set the clock and try again.

If it fails again and you or someone you know decide to look into it further, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can find exploded views and order parts by entering your model number at the
Sears parts site.

The magnetron probably has an extended warranty beyond the normal one year parts and labor warranty.

So I would consult your owner's manual or contact Sears for details on the warranty.

To get your owner's manual, just enter your full model number at the Sears parts site.

On the resulting page, look to the right for the blue "View Manuals" button.

That Sears-related site has many free manuals. While the manuals they list there are all free, they will ask you to register.

If yours is not listed there for free, you would have to order it through the
Sears parts site.
