Lg Microwave Parts

Lg Microwave Waveguide Cover
Genuine Lg part
By: Lg
Part Number: 3052W1A002A

This is a resin waveguide cover that sits inside the microwave cavity and shields the magnetron opening from food splatter and moisture. It allows microwave energy to pass through while protecting internal components. Replace this cover if it is cracked, burned, warped, or if you notice arcing or sparking during operation.

Do-It-Yourself Stories from Customers like You Arcing from the magnetron intermittantly   Peter V. • Georgetown , KY • September 29, 2015

I searched the web and it seemed that many people had a similar problem when gunk got on the waveguide plate/cover. When I removed the cover, one of the plastic latches broke so rather than just trying to clean the plate, I had to order a new one. The new one arrived in just a couple of days, I put the plate on and at least for the last few days, no more arcing. <$10 fix for my over the stove microwave. Read more

Lg Thermistor (Temperature Sensor)
Genuine Lg part
By: Lg
Part Number: 6322W2A001A

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

  • Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
  • Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
  • Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
  • Use when the existing sensor fails to report correct temperatures or the part number matches.
What's included: One thermistor sensor. Install notes:
  • Always disconnect power to the appliance before servicing to avoid shock or damage.
  • The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
  • Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

Do-It-Yourself Stories from Customers like You Microwave would not microwave   Richard E. • Cape Coral , FL • January 05, 2020

Replaced the Humidity sensor, Thermistor and door switches. I replaced these thinking the problem was one of the items but didn't want to trial and error one part at a time. Plus the cost was reasonable so if these didn't help I wasn't out a lot of money. I sense the door switch was the problem. Replaced all items and the microwave works great. Thanks for the advice and the cost of the parts. Read more

Do-It-Yourself Stories from Customers like You Kennmore elite microwave with f5 error code   Julius D. • Oxford , PA • February 11, 2017

When Microwaving food, the display panel would seem to act normal, but the typical microwave sound would be absent. No microwave action would occur. Eventually an F5 code would display. Problem was the upper door switch. Found it by opening up the cabinet, removing the display panel (1 screw and a couple of plugs) and testing all three micro switched with a meter.
