How to Install Microwave Power Cord 5304440028 in a Electrolux Microwave
Quick answer: Unplug the microwave and take it down. Remove the outer cabinet, discharge the high-voltage capacitor, then photograph and disconnect the old cord at the terminal block and ground screw. Feed 5304440028 through the strain relief, connect its wires the same way, reassemble and test.
The power cord 5304440028 is the three-wire cord that brings household power from the wall outlet into your Electrolux microwave. It enters through the back of the cabinet, is gripped by a strain relief bushing, and connects to the terminal block and chassis ground inside. A cord with a cracked jacket, a scorched plug or a break inside the insulation makes the microwave go dead, work only when the cord is wiggled, or trip the breaker. This cord is listed for over-the-range models such as FGMV173KBC, CGMV173KBC, EI30BM55HSA and EI30BM55HBA, and it supersedes the codes 10FFMICF01, 10FFSCRB01, ECOM and ECOP.
This is an advanced job, not because the wiring is complicated but because you must open the microwave cabinet to reach the cord connections, and the high-voltage capacitor inside can hold a dangerous charge after the unit is unplugged. Discharge it before touching anything, work from a photo of the original connections, and refit the strain relief properly so the cord can never pull loose from its terminals.

- Unplug the microwave before doing anything, and treat the inside as live until the capacitor has been discharged.
- Discharge the high-voltage capacitor by bridging its terminals to the chassis with an insulated tool; a meter should then read zero.
- Never run the microwave with the cabinet removed.
- The green or bare ground wire must be reconnected to the chassis screw; without it a fault can make the whole cabinet live.
Tools and Parts You Need
- Phillips and Torx screwdrivers for the cabinet and terminal screws
- Insulated screwdriver with a jumper lead to discharge the capacitor
- Needle-nose pliers for push-on terminals and the strain relief
- Multimeter to check the old cord and confirm the discharge
- Phone camera for the wiring photo
- Helper and a padded surface for the microwave
- Work gloves and safety glasses
Step-by-Step Installation
- Unplug and take the microwave down Unplug the cord. On an over-the-range model, have a helper hold the microwave while you remove the bolts through the upper cabinet, tilt it forward off the wall plate and set it on a padded bench with the back accessible.
- Remove the outer cabinet Take out the screws around the back and sides of the wrapper and slide it off. Locate the point where the cord enters through the rear panel and follow it to the terminal block.
- Discharge the capacitor Find the large cylindrical capacitor near the transformer. With an insulated screwdriver connected by a jumper to the chassis, touch each terminal for several seconds, then bridge the terminals together. Confirm zero with a meter.
- Photograph and disconnect the old cord Photograph the terminal block and ground screw. Remove the ground screw, then pull or unscrew each of the two remaining cord wires from the block, noting which terminal each colour used.
- Release the strain relief Squeeze the strain relief bushing with pliers to release its tabs and push it out of the rear panel, then pull the old cord out through the hole.
- Feed in the new cord Pass the stripped end of 5304440028 through the rear panel hole, fit its strain relief into the hole and squeeze it until it locks. Pull gently on the cord from outside to confirm the relief holds.
- Connect the wires Attach the two power wires to the terminal block exactly as in your photo, and fasten the ground wire under the chassis ground screw. Tug each connection to confirm it is tight.
- Reassemble and test Refit the cabinet with every screw, rehang the microwave and plug it in. Confirm the clock lights, then heat a cup of water for one minute to check normal operation.
Fit Checks Before You Call the Job Done
- Capacitor discharged and confirmed at zero before any wire was touched
- Strain relief locked in the rear panel and the cord cannot be pulled through
- Both power wires on the same terminals as the original cord
- Ground wire fastened tightly under the chassis screw
- Cabinet fully reassembled before the plug goes in
- Clock lights and water heats normally
Common Mistakes to Avoid
Skipping the capacitor discharge The cord terminals sit near the high-voltage section. Discharge the capacitor first, every time.
Leaving out the strain relief Without it, a tug on the cord pulls the wires off the terminals or bares them against the cabinet. Fit and lock it before connecting.
Forgetting the ground wire The green wire under the chassis screw is what keeps the cabinet safe during a fault. It is not optional.
Reversing the two power wires Follow the photo so line and neutral land where the original cord had them. The microwave's fuse and switches depend on it.
Troubleshooting After Installation
Microwave is completely dead after the new cord Unplug and confirm both wires are tight on the terminal block. Check the outlet with another appliance and check the microwave's line fuse.
Breaker trips when plugged in A wire is touching the chassis or the power wires are reversed. Unplug, discharge and compare each connection with your photo.
Cord feels loose at the back The strain relief did not lock. Unplug, open the cabinet and reseat the relief until it snaps into the panel.
Plug warms up in the outlet The outlet contacts are worn, not the cord. Have the outlet replaced before using the microwave.
Care Tips After the Repair
- Never pull the plug out by the cord; grip the plug body.
- Route the cord so it does not rest on the hot vent at the top rear of the microwave.
- Inspect the plug and jacket whenever the microwave comes down for cleaning.

Frequently Asked Questions
Which microwaves use power cord 5304440028?
It is listed for Electrolux and Frigidaire over-the-range models such as FGMV173KBC, CGMV173KBC, CGMV173KWC, EI30BM55HSA, EI30BM55HBA and EI30BM55HZA, and replaces 10FFMICF01, 10FFSCRB01, ECOM and ECOP. Confirm your model number on the label inside the door.
Can I just splice a new plug onto the old cord?
No. A splice outside the cabinet has no strain relief and no protection. Replace the whole cord with the listed part.
Do I really have to discharge the capacitor to change a cord?
Yes. The cord connections are inside the same cabinet as the high-voltage components, and you will be working within reach of them.
How do I know the cord is the problem?
With the cord disconnected inside, a meter should show continuity from each plug pin to its wire end. An open reading or one that changes when the cord is flexed means the cord has failed.
