MU30RSC

What we most often repair on units like this

1. Wear in the exhaust fan or blower, or a clogged grease filter, reduces venting
2. Door hinge or latch wear keeps the interlock switch from being satisfied
3. An aging keypad, turntable motor or magnetron

Kitchens built around a Professional Series range from an earlier era may have the MU30RSC overhead. ManualsLib’s entry for its Thermador installation instructions treats it as a true 30-inch microwave for mounting above the range. A near-identical number, MU30RSU, has its own entry and looks like a twin. Neither is the current MU30WSU.

Sitting over a cooktop means ventilation duty, so this generation has a complaint that ordinary microwaves do not: a grease filter that clogs and an exhaust blower that wears. A kitchen that lingers with cooking odor is a clue that airflow, not the microwave, needs attention.

The shared list of age problems applies too. The door can lose its latch and fail the interlock switch, the keypad can turn flaky, and the turntable motor and magnetron both wear with years of use.

Key features

• Professional Series microwave from Thermador for mounting above the range, 30 inches wide, ancestor of the current MU30WSU
• Thermador's own installation instructions establish it as a real over-the-range microwave oven in that series
• A nearly identical model number, MU30RSU, is documented alongside it
