PRG366 Thermador Range - Overview

The sole review for this part by Andrew was most helpful and accurate with one exception: he said that there were two nuts Which needed to be removed in order to pull off the front knob panel. There were actually two on each end for a total of four, which confused me, as I wondered if I had the right ones. Another thing that would be helpful for somebody considering doing this repair is to know that it takes a deep quarter inch socket With two 6 inch extensions to reach these nuts through holes in the interior side panels. Also, take a look at the replacement potentiometers, and you’ll see that there’s a slot that can be lined up so that they can be pulled off the side of the shaft rather than off the front of the shaft. This repair took me about six hours. I’m mechanically inclined and work methodically, but since I’ve never done this repair before it was quite time-consuming.

Removed knobs and venturies. Unplugged electrical inputs. Lifted top plate. Replaced potentiometer. Replaced parts and plugged in electric supplies. Tested. Piece of cake, except for locating replacement potentiometer.

Remove slide racks from oven. At the back right corner of oven unscrew heat sensor probe. Access rear of range. Remove screws holding back panel. Find wire from temperature probe where it passes through back wall of over and unclip it pulling probe wire and probe out back of oven. From the inside of oven, push chopstick through hole probe wire was routed through, to find hole in back wall of oven. Once chopstick is visible from back of oven, with chopstick enlarge hole through visible insulation. This is the opening the new probe wire needs to be routed through. From inside oven push new wire, using chopstick, through this hole and reattach wire at back of oven using the plastic clip on the wire. From inside oven screw probe to back of oven wall, reattach outside panel to back of oven, turn gas back on, plug range back in, check oven operates, and push range back in place, reinstall racks. You may have to remove oven door if you have trouble reaching to the back of the oven to access the probe. YouTube videos are easy to find showing how to do that.
