Removed from cabinet. Confirmed electric was good at outlet. Removed top panels and saw that thermo sensor had “cooked” and took wires with it.
Called several local repair services and all were booked for at least 2 weeks. Checked parts available at AppliancePartsPros, educated guess for parts and they were delivered in less than 72 hours.
Fairly easy to replace the sensor and wires. Tried it “open” and all seemed good. Put covers back on and back in the cabinet. And it’s been working fine so far.
