Genuine Lg part
By: Lg
Part Number: 6600W1K001C
The Interlock Door Switch is an OEM part for LG microwaves. It is a safety component located on the door of the microwave designed to prevent the microwave from operating unless the door is securely closed. The interlock door switch works with the microwave's electronic control board to sense when the door is open or closed and allow or disallow operation accordingly.
Causes of a bad interlock door switch can include normal wear and tear from repeated opening and closing of the microwave door over time.
Symptoms of a bad interlock door switch include:
- The microwave runs or heats with the door open
- Error codes or diagnostic messages related to door sensors on the control board
- The microwave fails to operate even when the door is securely closed
This OEM LG part is also compatible with some Sears/Kenmore microwaves.

Came up with next control item upstream and tallied that item failure with percentages of successful repairs, (4 mins.) door safety switch.
Since I had to change out the most likely of the 3 and since I was already was going to be into the switch panel I ordered all 3 and swapped them all out to cover my butt, as they were...

Selector knob or dial stopped working? This encoder board translates rotary control input into signals. Moderate DIY repair requires control panel removal.
Do-It-Yourself Stories from Customers like You
Selector knob stopped functioning Jeffrey E. • Plymouth , MN • September 03, 2016
Replaced the "Encoder Board". My GE Advantium control panel came of fairly easily. There was 2 screws on top to remove a vent director giving access to a single screw that held the control panel in place. Once I removed that screw, I had to slide the control panel upwards by about 1/2" before it came off. At this point, I took several photographs of the wire connections to make sure I could reassemble them correctly... there were many! After unplugging the wire harnesses and connections, I...

Kitchen aid architect ii microwave turntable stopped rotating Stephanie M. • Colorado Springs , CO • March 25, 2017
First, it was going to cost $95 for an appliance guy just to look at it! I figured there would be an upcharge on the parts + labor on top of the $95, so I took a chance & decided my husband & I could fix it cheaper; we were right, but it was a 3 week process (luckily, we have another microwave in the basement we were able to use in the meantime). I googled the microwave model #, then price checked the same item I thought we needed; printed off the diagrams of the various microwave "systems" &...

Microwave blew line fuse Gerald G. • St. Louis , MO • August 05, 2019
It took a long time to determine the problem but eventually I discovered that the plastic bracket (latch hook) that held the three door-switches showed appreciable wear from repeated door openings and closings. This wear stopped the door from sealing properly and the door switch safety mechanism blew the line fuse. I replaced the worn bracket (AP6230612) as well as the plastic latch mechanism (AP4553585) on the door that engages this bracket (and of course the fuse too) and the microwave now...

Genuine Frigidaire part
By: Frigidaire
Part Number: 5304493153
The Door Switch is an OEM replacement part for Frigidaire wall ovens. It is a component located on the oven door that detects when the door is opened and closed. The door switch works alongside the control board to regulate oven operations based on door position.
Symptoms of a bad door switch can include:
- Oven failing to automatically go into bake or warm modes after door closure
- Interior lights not turning on when the door is opened
- Control buttons/display remaining constantly lit instead of dimming
- Oven not heating or functioning properly in different modes
Causes relate to normal wear over extended use as the door switch mechanism cycles with frequent door openings and closings. Moisture exposure or impacts could also degrade switch performance.
This OEM Frigidaire switch is compatible with Amana, Jenn-Air, KitchenAid, and some Electrolux wall oven models as well.

Frigidaire microwave oven lights and timer work but oven doesn't heat Reese F. • Essex Junction , VT • August 16, 2015
I diagnosed this problem via the web and the advice was spot on. The problem was a failure of the bottom door switch. I used a multimeter to verify that the switched never closed properly. It took me a minute to figure out how to remove the old switch (press a release tab under the switch while simultaneously rotating counter-clockwise). That was about the most difficult part of the repair.

Genuine Ge part
By: Ge
Part Number: WB27X32849
The Relay Board is an OEM part for GE microwaves. It controls the passage of proper voltage levels for various microwave components during operation.
Installed internally, this board transmits power signals to run the magnetron, fan, and lighting systems as directed by the selected cooking settings. Precise switching of voltages is required for consistent and balanced microwave radiation.
Symptoms of a faulty relay board include:
- Intermittent or unpredictable power level adjustments
- Magnetron fails to turn on or fluctuates excessively
- Light not illuminating properly
- Fan speed irregularities
- Microwaves not properly heating foods
Causes can be damage from liquid intrusion, heavy usage over time stressing the relays, or component failures within the board itself.
Replacing with this genuine OEM GE part restores optimized power routing to maintain consistent microwave functions. Compatible models also include some Hotpoint, RCA, and select Kenmore products.

Genuine Ge part
By: Ge

- Part of the safety interlock system that stops operation if the door opens mid-cycle
- Replace if the switch fails a continuity check or shows heat or terminal damage
What's included: 1 microswitch
- Disconnect power before service; microwave capacitors can retain a dangerous charge
- Note wire positions and move them to the same terminals on the new switch
- Ensure the door latch cleanly actuates the switch; test operation before reassembly
