Browse microwave thermal cutoffs at Exact Replacement Part for the application specified in each listing. These components interrupt an electrical circuit under specified fault conditions. This collection helps homeowners and service technicians narrow their search by application and part number. Product availability and included components are shown in each listing.

Common symptoms to investigate

Issues that may prompt inspection include loss of operation or heat after a confirmed open protective device. These observations are starting points for troubleshooting, not proof that a particular part has failed. Check the appliance service information and confirm the cause before ordering; wiring, installation, maintenance or another component may produce similar symptoms.

How to choose the correct replacement

• Match the exact current, voltage and temperature ratings; the cause of the original failure must also be corrected.
• Compare the original part number with the replacement references stated on the product page. Similar appearance or an appliance brand name alone does not establish fit.
• Check photos, dimensions, connections and included hardware. Kits and individual components may be sold separately.
• If fit is uncertain, contact us with the part number and a clear photo of the appliance model and serial label before placing an order.

Non-OEM aftermarket disclosure

The replacement parts in this collection are aftermarket, non-OEM products. They are not represented as original parts made by the appliance manufacturer. Manufacturer names, model numbers and original part references are used only to identify the intended compatible application. Compatibility applies only where specifically stated in the individual listing; no universal fit, manufacturer endorsement or equivalence in performance is implied.

Installation and ordering help

Microwave ovens contain high-voltage components that can retain a lethal charge after unplugging. Internal diagnosis and repair must be performed by a qualified microwave technician. Do not bypass door interlocks or operate a microwave with a damaged door, arcing or a damaged waveguide cover.
