The MOH230 is the MOH-series version of the Discovery double oven. Many owners call us about grease or haze trapped between the door glass panes, which is not a failure but spoils the look of the oven. We can take the door apart and clean or replace the inner glass without affecting its seal.

The EORS130 is one of the ovens Dacor’s Renaissance Wall Oven Service Guide was written for, so its error codes are unusually well documented: C-prefixed control errors such as C23 and C33 for board overheating, and U-prefixed oven errors such as U30 for an open sensor. That guide’s test values make diagnosis quick. The oven […]

The PO230 is listed under several finish suffixes, such as AG, BU, GN and SG, and visible parts are specific to each finish. Internal parts are shared with other Discovery ovens and remain easier to source. For colored ovens we confirm the exact finish code before ordering handles, trim or keypads.

The DOC30M977D puts a 1.9 cu. ft. speed oven, microwave plus convection for searing, broiling and air frying, above a 4.8 cu. ft. steam oven. Its code table adds C-10 for the speed oven’s cooking sensor, which no single-cavity Dacor oven uses. The upper cavity holds a microwave high-voltage circuit, so we discharge and test […]

On the EORD230, every oven code carries a letter that says which cavity reported it: U for upper, L for lower. An L30, for example, means the lower oven sensor reads open, and the upper oven usually keeps working. C76 is the code to know if a control has been replaced: Dacor’s guide says it […]

The MCS130 uses Dacor’s classic ERC control, the one Dacor’s Tec-Line documented with failure codes F0 through F8. An F4 is worth knowing: Dacor warns that an open sensor can make the bake keys seem dead, which looks like a failed clock but is a sensor. These ovens respond well to methodical testing. Dacor’s own […]

Dacor’s Transitional combination oven, the DOC30P977D, shares its layout with the Contemporary DOC30M977D: a 1.9 cu. ft. speed oven over a 4.8 cu. ft. steam oven, 40 amps at 240 or 208 volts. Dacor published a 93-page service manual for this series, and its part-by-part tests shorten diagnosis. Owners mostly notice the upper oven first, […]

The EORS127 shares its control and codes with the 30-inch EORS130. The most common owner-level issue is C01, a keypad membrane that registers a key held down for two minutes, which Dacor’s service guide traces to the membrane or its connector. Membrane keypads for these ovens are color-matched parts. We confirm the finish before ordering.

The MCD230 is the double version of the Millennia classic oven. Dacor’s diagnostic manual devotes a page to the lower oven ERC harness, and on these doubles a lower oven that stops responding is often traced to that harness rather than the ERC itself. F6, an EEPROM checksum error, is the other code to know. […]

The DOC30T977D is a combination oven: a 1.9 cu. ft. microwave-convection speed oven sits over a conventional 4.8 cu. ft. lower oven. Dacor’s user manual for it prints the combination-oven code table, C-10 included, on pages 80 and 81. Speed ovens depend on a chain of door switches before the microwave will run. A door […]
