How to Install Microwave Installation Hardware Kit 5304464349 in a Frigidaire Microwave

Quick answer: Use the template to locate the mounting plate on the wall studs, drill the cabinet-bottom holes for the two top bolts and the cord, hang the microwave on the plate hooks, then drive the bolts through the cabinet until the unit sits tight and level.

Installation hardware kit 5304464349 supplies the fasteners an over-the-range Frigidaire microwave needs to hang safely between two cabinets: the wall plate screws and anchors, the long top bolts that pass through the bottom of the upper cabinet, and the washers and small exhaust adapter screws. It is ordered when a microwave changes homes or the original box hardware was lost, and it replaces kit codes 10FFMICF01, 10FFSCRB01, ECOM and ECOP.

This guide covers hanging Frigidaire over-the-range models such as FGMV173KBC, CGMV173KWC or EI30BM55HSA using this kit. The job is mostly careful measuring and drilling, but the oven is heavy and awkward, so plan on a helper. Confirm the kit matches your model number on the rating label inside the door frame before drilling.

⚠️ Safety First
  • Switch off the breaker feeding the outlet inside the upper cabinet before you cut or drill near it.
  • An over-the-range microwave is heavy; never try to hold it on the wall alone while you start the bolts.
  • Wear safety glasses when drilling upward through a cabinet floor because chips fall straight into your face.
  • Keep the range and cooktop turned off and cold while you work above it.

Tools and Parts You Need

  • Cordless drill and a set of drill bits for wood and drywall
  • Phillips screwdriver and a socket or wrench that fits the top bolts
  • Stud finder and a 4 foot level
  • Tape measure and a pencil
  • Painter's tape to hold the paper template in place
  • Safety glasses and work gloves

Step-by-Step Installation

  1. Unpack and sort the kit Lay out every piece from kit 5304464349 and compare it with the hardware list in the installation sheet. Separate the long top bolts, the wall plate screws, the washers and the small exhaust adapter screws so nothing is mixed up during the lift.
  2. Locate the studs and mark the wall Run a stud finder across the wall between the cabinets and mark the stud centers with pencil. Tape the wall template to the back wall, aligning its bottom edge with the top of the range hood opening and checking that it sits level.
  3. Mount the wall plate Hold the metal mounting plate against the template marks and drive the supplied screws into at least two studs. Where a stud is not available, use the toggle anchors from the kit in the marked holes so the plate is solid on every side.
  4. Drill the cabinet bottom Tape the top template to the underside of the upper cabinet, aligned flush with the front edge. Drill the two bolt holes and the larger power cord hole where the template indicates, then remove the template and clear the sawdust.
  5. Prepare the exhaust Decide whether the microwave will vent outside through the top, out the back, or recirculate inside the kitchen. Rotate the blower motor and attach the damper or exhaust adapter from the kit as the instructions show for your chosen direction.
  6. Lift and hang the oven With your helper, tilt the microwave forward, feed the power cord up through the cabinet hole, and lower the back edge of the oven onto the hooks on the wall plate. The oven should hang there on its own while you steady the front.
  7. Drive the top bolts From inside the upper cabinet, slide the washers onto the long bolts and start them by hand through the drilled holes into the threaded bosses on top of the oven. Tighten alternately until the oven pulls up snug against the cabinet bottom without gaps.
  8. Restore power and test Plug the cord into the outlet inside the cabinet, turn the breaker back on, and run the microwave for one minute with a cup of water. Check the light, turntable, and fan, then run the exhaust fan and feel for airflow at the vent.

Fit Checks Before You Call the Job Done

  • The wall plate hooks engage the slots in the back of the oven and the unit hangs without your hands on it before bolts go in.
  • Both top bolts thread smoothly into the oven top; if a bolt binds, the cabinet holes are off and need to be enlarged slightly, not forced.
  • The oven front is flush with the upper cabinet face and the door swings fully open without hitting a cabinet or handle.
  • A level laid on the top of the oven reads level side to side and front to back.
  • The power cord reaches the outlet without being pinched between the cabinet and oven top.

Common Mistakes to Avoid

Skipping the stud finder Screwing the wall plate only into drywall lets the plate sag under the weight, cracking the wall over time. Hit studs wherever possible and use the anchors provided for the remaining holes.

Drilling without the template Guessing the hole positions leads to bolts that miss the threaded bosses on the oven. Always tape the template flush to the front edge and drill exactly where marked.

Tightening one bolt fully first Pulling one side up tight before the other twists the oven on the wall plate and can strip a boss. Alternate a few turns on each bolt until both are snug.

Forgetting to rotate the blower If the exhaust direction is wrong, the fan will roar but move no air. Set the blower before the lift, because it cannot be changed once the oven is hung.

Troubleshooting After Installation

The oven rocks or tilts forward after the bolts are tight The rear edge is not seated on the plate hooks. Loosen the bolts, lift the back slightly with your helper so the hooks drop into the slots, then retighten.

A top bolt spins but never tightens The bolt missed the threaded boss or the boss threads are damaged. Back it out, look up through the cabinet hole to realign, and use a fresh bolt from the kit if the threads are chewed.

Exhaust fan runs but no air leaves the vent The blower is aimed the wrong way or the damper is stuck. Remove the oven and reposition the blower and adapter according to the vent direction.

Care Tips After the Repair

  • Once a year, open the upper cabinet and check the top bolts for looseness caused by vibration.
  • Clean the grease filters under the oven monthly so the blower does not strain against clogged mesh.
  • Wipe steam and grease from the underside so moisture does not reach the wall plate screws.

Frequently Asked Questions

Does kit 5304464349 include the wall plate itself?

The kit supplies the fastening hardware; the mounting plate normally ships with the oven. Check your parts diagram for your model to be sure which pieces are included.

Can one person hang the microwave with this kit?

No. The oven must be held against the cabinet while the top bolts are started, which is not practical alone. Use a helper or a support jack.

Which codes does this kit replace?

It replaces kit codes 10FFMICF01, 10FFSCRB01, ECOM and ECOP, so any of those on an older invoice point to the same hardware.

Final Checklist

  • Breaker to the cabinet outlet turned off before drilling
  • Studs located and wall plate secured to at least two of them
  • Cabinet holes drilled with the template flush to the front edge
  • Blower rotated and exhaust adapter set for the chosen vent direction
  • Power cord fed through the cabinet before the lift
  • Both top bolts tightened alternately until the oven is snug
