KIEBK5607 Genuine Rotating Heater Board Spring for Mitsubishi Electric Fridges, French Door Flipper Mullion Spring

KIEBK5607 is a genuine Mitsubishi Electric spring for the rotating heater board, a part found on fridges with a pair of French doors. The rotating heater board is the hinged strip on the edge of one door that swings across to seal the gap between the two doors when they close. This spring holds the board in the right position as the door opens and shuts. Check KIEBK5607 against your fridge's parts list before ordering.

French door gap not sealing? Check the heater board spring

The rotating heater board, sometimes called a flipper or mullion, has a small heater inside to stop condensation forming where the two doors meet. Its spring makes sure the board folds flat when the door opens and swings into place as it closes. If the spring breaks or comes loose, the board may flop, stick out at the wrong angle, catch on the cabinet guide or stop the door shutting. You might see condensation, frost or drips along the door join, or hear the board knocking. A new spring often fixes it without replacing the whole board.

Replacing the spring

Switch the fridge off at the wall before working on the heater board, as it contains a heater and wiring. With the door open, remove the board's end cap or hinge cover to reach the spring, noting which way the spring is wound and how its ends hook on. Fit the new spring the same way, then open and close the door several times to check the board folds and swings cleanly.

Questions about this part

Do I need the whole heater board or just the spring?

If the board flips freely, isn't cracked and the heater still works, the spring alone is usually enough. If the board is broken or the heater has failed, the board itself needs replacing. Our record lists the rotating heater board separately as KIEBK5050.
