Frigidaire Microwave Filters

Below are the types of filters you may have on your Frigidaire microwave and how they work.

  • Grease Filter
  • Air filter
  • Charcoal filter

Microwave Grease Filter

If your microwave is above your stovetop, grease flies onto it from the stovetop. Microwave grease filters catch grease that flies into the microwave from the stovetop. The filters catch the grease in the air, preventing the fan from becoming clogged.

Broken, missing, or undersized grease filters are prone to accumulating highly flammable grease deposits. You’ll only need a grease filter if you have an over-the-stove microwave.

Microwave Air Filter

 Microwave air filters help clean the air circulating within the microwave during cooking.

Microwave Charcoal Filter

Frigidaire Microwave Light Bulbs

Frigidaire Microwave Light Bulbs

The microwave’s interior lighting is essential and is provided by the light bulb. It helps to see the inside of the microwave.

Having a wrong light bulb in the microwave can be very dangerous; at best, they provide low or no light at all, and at worst, they could blow up the microwave, leading to potential damages. So it’s important to pay good attention when getting a light bulb for your microwave.

Troubleshooting Frigidaire Microwave Light Bulbs

Burned-Out Light Bulb

The bulb itself may be burned out, one of the most common causes of a microwave light bulb not working. To determine whether this is the issue and to resolve it, do the following:

  • Unplug the microwave.
  • Turn off the power to the microwave at the breaker point.
  • Locate the vent in your microwave.
  • Unscrew the screws to remove the panel.
  • Remove the cover from the box containing the halogen light.
  • Unscrew and replace the bulb with a new one if the bulb is bad.

Problem with the Light Socket

A fault in the light socket could also cause the microwave light bulb not to work. Before examining or replacing the light socket, you must first replace the light bulb using the above procedure.

If the light still does not function, a multimeter will be required to check or test the socket for continuity. If there is no continuity in the light socket, you may need to replace it or have it fixed by a professional.

Problem with the Main Control Board

An issue with the main control board could also be the cause of your microwave’s light bulb not working. Check to make sure bulb, wiring, and sockets, are all intact and functional before moving on to the main control board. If all the previous is fine, use a multimeter to test the control board.

This will allow you to check if the main control board supplies the correct voltage to the light bulb socket. If not, you may need to replace it, which should only be done by a qualified professional or technician.

How to Replace Frigidaire Microwave Light Bulbs

  • To begin, disconnect the microwave or shut off the main circuit breaker.
  • Then, remove the bulb covering mounting screws from both positions under the microwave.
  • Remove the old bulbs and replace them with 30-watt appliance bulbs.
  •  Replace the bulb cover and mounting screws.

Frigidaire Microwave Glass Trays

The turning glass tray acts as insulation to prevent sparking. It rotates the food to heat it evenly and thoroughly. This cooking tray is made of transparent glass and may need to be replaced if the tray is cracked or broken. Without the tray, your food will not cook as evenly and will need to be manually rotated during heating.

Troubleshooting Frigidaire Microwave Glass Trays

Faulty Turntable Motor

The most common cause of a microwave turntable/glass tray not turning is a problem with the turntable’s motor.

You can use a continuity multimeter to check this. To do so, follow the steps below:

  • Remove the glass tray and support ring from the microwave by opening the door.
  • Remove the screws from the rear of the microwave with a screwdriver.
  • Squeeze the wire harness plug to disconnect it, then place the lower panel aside.
  •  Remove the turntable motor wires’ terminals using a screwdriver.
  • Check for continuity by connecting the motor’s terminals to the multimeter’s terminals.
  •  If there is no continuity, the motor might need to be replaced. If there is continuity, though, it could be another factor.

Damaged or Missing Glass Tray Drive Coupling

Another common cause of a non-turning microwave turntable/glass tray is a problem with the glass tray drive coupling. It’s possible to break or remove the coupler. Most ovens and microwaves have a round glass turntable with a roller guide and a motor-driven coupler. The majority of units include a three-sided coupler that detaches easily from the motor shaft.

  • To fix it, inspect the drive coupling for any damage. Gently remove it away from the drive motor shaft. If the coupler is damaged, it may need to be replaced.

Damaged Glass Tray Support

If your microwave’s turntable isn’t working, the glass tray support may be cracked or pulled off.

  • Gently pull out the drive motor shaft and inspect the tray support for any damage to solve this problem. You may need to replace it if it turns out to be damaged.

Damaged or Missing Roller Guide

A problem with the roller guide could potentially cause the microwave turntable’s inability to turn. This element is located right beneath the glass tray and aids in keeping the tray on track while rotating. This portion rotates the turntable with the help of the coupler.

A problem with the roller guide could potentially cause by the microwave turntable’s inability to turn. This element is located right beneath the glass tray and aids in keeping the tray on track while rotating. This portion rotates the turntable with the help of the coupler.

  • To troubleshoot, remove the glass tray and inspect it for cracks, damage, or wear to see if this is the case. You may need to replace it if it is worn out.

Clogged Particles Stopping Rotation

Certain particles may become lodged beneath the turntable, obstructing its motion. If you suspect this to be the case, you will need to clean the turntable properly.

  • First, remove the circular turntable guide as well as the glass tray.
  • Then, wash them both in warm soapy water to eliminate whatever was creating the clog.

Frigidaire Microwave Handles

Frigidaire Microwave Handles

Microwave oven handles aren’t always made of the most durable materials, and even the most durable ones can be damaged over time.

How to Replace Frigidaire Microwave Handles

Below are some quick instructions on how to replace a broken Frigidaire microwave handle.

  1. Remove the power cord from the outlet. Allow 60 seconds for the unit’s high-voltage capacitor to discharge. Note that this is simply a precautionary measure; the capacitor and other components stored inside the microwave’s exterior case may still be charged with a high voltage. Never take the outer case off the microwave housing or work on its inside.
  2. Completely open the oven door. Examine the door’s interior panel, preferably with the model’s instruction booklet nearby. Using a flathead screwdriver between the inner and outer door panels at the top outside corner, remove the inner door panel if it is not screwed in place. To separate the panel from the door, slide the screwdriver along the top of the door. Remove four screws from each corner of the inner panel is held in place by screws. To access the screws, you may need to carefully remove the door from its hinges.
  3. Depending on whether the old handle is held in place by screws or nuts fastened onto threaded posts, unscrew it with a Phillips screwdriver or a nut driver. Take the handle off.
  4. Install the replacement handle, then push the panel against the door until it snaps back into place, or you can screw it back in place. It could take a few tips to get it to sit on the rim of the door.

Frigidaire Microwave Latch

Frigidaire Microwave Latch

The latch assembly is a release mechanism found on most microwave doors that keeps the door closed when the microwave is on or off. It usually has two hooks that connect to the microwave’s switch holder on the frame. The latch is essentially a plastic hook that captures or releases the door when you press the open button.

How to Replace Frigidaire Microwave Latch

Over time, the latch assembly undergoes wear and tear, which is entirely normal. If your microwave’s door no longer holds when you close it or refuse to open it, you need to replace the latch.

Tools Needed: Below are the tools you need to get started.

  • New door latch assembly kit
  • Flat-head screwdriver or putty knife
  • Phillips-head screwdriver

Below, you will find step-by-step instructions on how to replace your microwave’s door latch.

  • First, disconnect the Power Supply and make sure that the microwave is unplugged from the outlet, to reduce chances of electric shock.
  • Locate the Plastic Panel on the door and examine the interior of the microwave door by opening it and physically inspecting it.
  • Just within the door frame, a seam should be evident around the internal plastic panel. Small screws may or may not secure the plastic to the frame.
  • Separate the Plastic Panel from the Door Frame and remove any screws securing the plastic panel.
  • Gently work your way around the door with the thin edge of the flat-head screwdriver or the putty knife inserted into the seam.
  • Pry the plastic panel apart from the metal door interior with a gentle pry.
  • Set aside the plastic panel and any screws that were removed.
  • Remove the door latch and determine where it is located at the door frame’s edge. A lengthy molded plastic piece with two plastic “hooks” makes up the latch’s plastic component. It would be best to easily lift it out of the Door housing and towards you. A little spring should be sitting in an aperture in the metal at the bottom of the door. You can also get rid of this.
  • Inspect Original Parts. The spring is designed to attach to both the door’s metal frame and a little hook on the rear of the plastic door latch.
  • Remove the old latch and replace it with the new one. To hook and secure the spring, reinsert the latch into the door.
  • Extend the bottom end of the spring down along the side apertures in the door frame.
  • Around the borders of the plastic panel are built-in tabs. Replace the latch by aligning it with the frame and pressing along the edge until it snaps back into place. You can now re-plug the microwave and use it again.
