Wolf Legacy E Series Code RM EE Checksum Error: 07 0 27 relay module memory

What RM EE checksum error means

On Wolf Legacy E Series wall ovens from the SO30TE/PE generation, code 07 0 27 is the RM EE checksum error. The relay module's stored memory failed its integrity check, so the oven cannot trust its saved settings. Expect the oven to stop or refuse to start while the message shows. This legacy code is separate from the four-digit codes used on the newer SO3050TE.

Common causes of RM EE checksum error

Relay module memory (EE) failing its checksum
Corrupted stored data in the relay module
Relay module failure

✓ One safe check you can try

1. Turn the oven off at the breaker and wait two minutes. 2. Restore power and let the display start up fully. 3. Try a basic bake setting. 4. If 07 0 27 returns, leave the oven off and call us; do not open any panels.

! Why to stop there

Memory and relay module work needs board-level testing.
A one-time reset may hide a failing module that will return.
We give a written price first and a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

RM EE checksum errorRM EE checksum error questions

What does 07 0 27 mean?

It is the RM EE checksum error: the memory in the relay module failed its integrity check. The oven cannot rely on its stored data and typically stops.

Will a power reset fix it?

Sometimes a single reset lets the oven restart. If the code returns, the module itself is likely failing and needs testing or replacement. Keeping the oven off after a repeat avoids further stress on the module.

Is it a control panel problem?

This code points at the relay module, not the keypad. We check the module first so you are not charged for panel parts you do not need.
