How to Install Microwave Metal Rack 5304463180 in a Frigidaire Microwave

Quick answer: Open the microwave door, find the four rack supports molded or clipped into the cavity side walls, and hook the rear feet of rack 5304463180 in first, then lower the front feet onto their supports. Confirm the rack is level and does not touch the door, turntable or cavity walls before cooking.

The metal rack 5304463180 gives you a second cooking level inside a Frigidaire over-the-range microwave, so a casserole can heat below while a plate warms above. It sits on dedicated supports in the cavity side walls that are designed to keep the rack away from the metal walls and prevent arcing. The rack replaces earlier part numbers including 10FFMICF01 and 10FFSCRB01, and our fitment data lists it for 16 microwave models such as EI30BM55HSA and EI30SM55JSC.

Installing a microwave rack is easy, but it is one of those parts that is either exactly right or dangerous. A rack that is bent, resting on the wrong supports or touching the cavity can spark and pit the interior. This guide shows where the rack belongs, how to seat it properly, how to tell the front from the back, and what to check before the first use. No tools are strictly required, and the job takes only a few minutes.

⚠️ Safety First
  • Unplug the microwave or leave it switched off at the control while you fit the rack, so nobody starts it with your hand inside.
  • Never run the microwave with the rack touching a cavity wall, the door screen or the turntable. Contact causes arcing that damages the interior coating.
  • Do not use the rack if it arrives bent or with chipped coating; a damaged rack can spark even when positioned correctly.
  • Keep aluminum foil and metal containers off the rack; the rack itself is designed for microwave use, other metal is not.

Tools and Parts You Need

  • Flashlight to see the rack supports in the cavity walls
  • Clean microfiber cloth
  • Mild dish soap and warm water
  • Owner's manual for your model, if available, to confirm rack orientation
  • Level or a straight edge (optional)

Step-by-Step Installation

  1. Switch the microwave off Unplug the microwave or make sure the control panel is idle. Open the door fully and remove any food, the turntable if it is loose, and anything stored inside.
  2. Locate the rack supports Shine a flashlight along both side walls of the cavity. You will see two supports on each wall, one toward the front and one toward the back, usually molded plastic or metal tabs about halfway up the wall.
  3. Clean the supports and cavity Wipe the supports and the surrounding walls with a damp cloth. Grease on a support lets the rack slide and shift while cooking, which is a common arcing cause.
  4. Identify front and back of the rack Hold 5304463180 up to the cavity. The rack has hooked feet on the corners; the pair with the deeper hooks normally goes to the rear supports. If your manual shows a diagram, follow it.
  5. Hook in the rear feet Tilt the rack slightly, slide it in and set the rear feet onto the two rear supports first. Push back until you feel them seat.
  6. Lower the front feet Lower the front of the rack so the front feet drop onto the front supports. The rack should now sit level without any wobble when you press gently on each corner.
  7. Check clearances Look at all four sides and the door screen. The rack must not touch the side walls, back wall, ceiling or door. Rotate the turntable by hand and confirm nothing on the rack blocks it.
  8. Run a short test Place a cup of water on the turntable, close the door and run the microwave for 30 seconds. Watch for any sparks around the rack. If you see or hear arcing, stop immediately and reseat the rack.

Fit Checks Before You Call the Job Done

  • All four feet rest on a support; the rack does not hang from only three points.
  • The rack sits level and does not rock when pressed on any corner.
  • There is a visible gap between the rack and every cavity wall and the door screen.
  • The turntable spins freely under the rack with no contact.
  • The rack coating is intact all the way around, with no bare metal at the feet or corners.

Common Mistakes to Avoid

Setting the rack directly on the turntable The rack belongs on the wall supports, never on the glass tray. On the tray it can touch the walls as the turntable rotates and cause arcing.

Installing the rack backwards Rear and front feet are shaped differently. Reversed, the rack tilts and one corner may float above its support and vibrate against the wall.

Leaving the rack in during regular cooking Frigidaire and Electrolux manuals call for removing the rack when you only cook on one level. An empty rack absorbs energy and can arc.

Using a rack from a different model Racks look alike but differ in width and foot spacing. Use only the part listed for your model, such as 5304463180 for EI30BM55HSA and similar units.

Placing foil-covered dishes on the rack Foil close to the rack creates sparks. Use glass or microwave-safe containers on both levels.

Troubleshooting After Installation

Sparking around the rack while cooking Stop the microwave. Remove the rack, inspect for bent corners or chipped coating, clean the supports and reinstall so all four feet seat fully with clear gaps to every wall.

Rack rocks or rattles during cooking One foot is not on its support or the rack is reversed. Take it out and hook the rear feet first, then lower the front.

Rack will not fit between the supports Confirm your model is in the fitment list for 5304463180. A rack meant for a different cavity width will be too tight or too loose.

Food on the rack heats unevenly That is normal for two-level cooking. Use the rack for warming or reheating, place the denser food on the turntable, and swap positions halfway through.

Care Tips After the Repair

  • Remove the rack and wash it by hand with mild soap when you clean the cavity; a dishwasher can chip the coating.
  • Inspect the coating monthly and stop using the rack if bare metal shows at the feet.
  • Store the rack outside the microwave when not in use, in a spot where it will not get bent.
  • Wipe the wall supports each time you clean the interior so grease never builds up under the feet.
