MED272

What we most often repair on units like this

1. Breaker too small for the documented 40A requirement
2. An element or thermostat in one cavity gives out on its own
3. Door seal or hinge wear on either oven, which shows up more in the narrower cabinet
4. Timer or clock assembly of the electromechanical type stops working
5. Wiring at the junction box corrodes

Narrow cutouts are where the MED272 belongs: it is a legacy electric double wall oven from Thermador, built in and 27 inches wide, a slimmer sibling to the 30-inch MED302 built on the same dual-voltage platform. Thermador’s installation manual calls for a 40A circuit, the same figure given for the ME302 and MED302 of that generation.

With two ovens in one cabinet, the first useful step is working out which oven, upper or lower, is responsible, before we suspect anything shared such as the control or the wiring. Each cavity generally has its own elements and thermostat, even though the pair draws from a single circuit.

Door seals and hinges get extra attention in a unit this narrow, and we finish with the timer or clock assembly and the connections inside the junction box. The supply is a four-wire, single-phase feed at 208V or 240V AC.
