Wolf Legacy E Series wall ovens in the SO30TE/S/TH and DO30TE/S/TH generation show Error 07 0 32 as RM HIV Fuse Error. The relay module reports a problem with its HIV fuse, so loads on that side may lose power. You see the code, and heating or other functions may not work. Here the 0 is fixed, which marks a control-level message instead of a single cavity.
1. Turn the oven off, then wait until you can safely touch the door glass. 2. Use the breaker to remove power for one minute, then restore it. 3. See whether the oven starts and heats on a short bake. 4. If Error 07 0 32 comes up again, call us and leave the oven off until we arrive.
It is the HIV fuse on the relay module, as the display says. The low-voltage fuse has its own message, Error 07 0 31, so the number tells us which fuse to look at.
If the fuse feeding the heating side is open, those loads have no power and the control reports the fuse error until the cause is repaired.
A breaker reset cannot close an open fuse. It may restart the display, but the oven will report the fuse error again until the fuse and its cause are handled.
A technician diagnoses it on site and gives you the price in writing before any work starts.
