KitchenAid KHMS145K Microwave Oven Repair
The KHMS145K is an older KitchenAid microwave, and the stainless version is also sold as KHMS145KSS. Units like this usually sit in a cabinet cutout or over a range, where cooking vapor and grease reach the vents every day. After this many years the cooling path is the first place we look.
When a KHMS145K stops partway through a cycle, we pull it from its mounting, clean the fan path and filters, and run it under load before touching any electrical part. A dark burn mark on the waveguide cover tells us the cavity has been arcing, and that cover is replaced rather than cleaned. We also look at bare metal where the paint has worn, because rust there spreads.
You get a written price before any work starts, and the repair carries our 30-day workmanship warranty.
We start with the cooling air path. Grease on the vents and fan makes the oven overheat and shut down on purpose, so we clean it, then run a timed load to see whether the shutdowns stop.
Please stop using it. A scorch mark at the waveguide cover means energy is arcing there. We replace the cover, check the cavity wall behind it, and test heating before returning the oven to service.
Yes, if bare metal shows. Rust can flake and spark under microwave energy. We assess the size of the worn area and tell you in writing whether touch-up, a cavity repair or replacement makes sense.
