Built-in and drawer microwaves rely on door or drawer interlock switches and heating electronics working in sync — the appliance won’t run at all if the safety switches don’t agree the door is properly closed. A keypad or control problem is common and rarely urgent, but a unit that runs normally yet produces no heat usually means the magnetron itself has failed, which does need prompt attention.
Because these units are set into cabinetry rather than sitting on a countertop, our technicians work carefully around surrounding trim and drawer slides so a repair doesn’t turn into a cabinetry problem.
