An over-the-range microwave doubles as the range hood. Its filters get dirty faster than most owners realize, and a neglected fan works harder.

A microwave with a lit display and a spinning turntable but cold food has a high-voltage problem inside. Owners can rule out a few things, but should never open the cabinet.

The FFMV1846VS doubles as a range hood, so service covers both cooking and ventilation. When the fan and lights work but food does not heat, the high-voltage circuit is suspected. When the microwave will not start at all, door interlock switches are a common cause. Microwaves store high voltage even when unplugged, so the cabinet […]

The FMOS1846BS combines microwave and hood ventilation. A fan that turns on by itself can be the automatic heat-sensing feature responding to heat from the range below, which is normal behavior on many over-the-range units. Sparking inside the cavity should stop use right away. It can be caused by metal in the cavity, damaged interior […]

The GMOS1964AF uses sensor cooking to estimate when food is done by detecting steam. If sensor cycles stop too early or too late, covering food correctly and using the right container are the first things to check. Loud humming during operation can be normal transformer noise, but a new loud buzz or burning smell should […]

The FGMV176NTF is a Gallery over-the-range microwave with a PureAir filter for recirculating installations. Lingering odors often mean the charcoal filter needs replacement according to the owner’s manual schedule. If the touchpad stops responding, the control lock should be ruled out first. After that, the keypad and control board are tested.

The FGMV175QF is an earlier Gallery over-the-range microwave. Units of this age commonly need door switches, turntable motors or light components, which are usually repairable if the rest of the microwave works well. A microwave that stops mid-cycle may be overheating or detecting a door switch issue. Microwaves store high voltage even when unplugged, so […]

The FFCE1638LS is a countertop microwave, so diagnosis is simpler than for over-the-range units. Door release and switch issues are common, and many owners replace rather than repair when high-voltage parts fail. A technician can help you decide whether repair makes sense. Microwaves store high voltage even when unplugged, so the cabinet should only be […]

The PMBD3080AF is a built-in convection microwave with a drop-down door. Because it combines microwave and convection functions, a technician tests each mode separately to find whether the failure is in the microwave system, convection element or fan. Built-in units must be removed carefully from the cabinet opening, so repairs involving the chassis should be […]

The FGMO205KF is a built-in microwave designed for cabinet or wall installation. A microwave that trips the breaker should not be reset repeatedly, as it can indicate a short in a high-voltage component. Microwaves store high voltage even when unplugged, so the cabinet should only be opened by a technician. A technician can safely remove […]
