An E5 on a legacy Thermador CT or CMT oven with the Dreefs control points at the control board: the first table says it is too cold, too hot, or defective, and a second page simply says replace the control board. Both heat and microwave shut off, and clean and cooking use are disabled. The message stays on the display until the board is repaired and the oven is powered back up.
1. Begin at the selector: OFF, plus a slight counterclockwise tweak to silence the alert. 2. Let the oven and the surrounding cabinet cool for a while. 3. Restore power and try one short bake. 4. If E5 comes straight back, it will stay until repaired, so switch the oven off at the breaker and call us.
The source says too cold, too hot, or defective, so temperature is one reading. Letting the oven rest and restarting is a fair single test. If E5 returns quickly, the board itself is the likely issue.
The control shuts off heat and the microwave and disables clean and cooking use until repair. It is protecting the oven because the board that manages everything cannot be trusted at that moment.
No. The source points at the control board, not the cabinet or cavity. We test first, then quote the repair in writing so you can compare it with replacement before agreeing.
Our technician checks it in your home and hands you a written price before touching anything.
