The ME271 is the 27-inch single-oven counterpart to the 30-inch M301/ME301 from the same Thermador generation, sized for a narrower cabinet cutout but built on the same dual-rated 208V/240V electrical platform. Thermador’s installation manual documents this model’s required circuit as 30 amps, the same figure listed for either voltage supply.
Since this is a legacy unit with no smart features to trouble-shoot, most service calls come down to mechanical wear: heating elements, door seals, and the aging timer or clock assembly typical of ovens from this era, plus a check of the wiring connections at the junction box for corrosion on any oven this old.
Key Features
- 27-inch single built-in electric wall oven
- Dual-rated for 208V or 240V AC, 4-wire single-phase supply
- Documented circuit requirement: 30A (same rating listed for both 208V and 240V)
- Narrower 27-inch cutout distinguishes it from the 30-inch ME301 of the same generation
Most Common Issues on This Model
Breaker or circuit mismatch for the documented 30A requirement
Heating element failure after long-term use
Aging door seal or hinge wear affecting bake consistency
Timer/clock assembly failure on older electromechanical controls
Wiring corrosion at the hardwired junction box
