Thermador PRD484EEG/05 (Small Oven)

[jeff@beckettandhensley.com]

I have a Thermador PD48.  It has a large oven (PRD484EEG205) and a small oven (PRD484EEG/05).  The large oven works fine.  When the small oven is turned on, it kicks back off and begins a light sequence code of:

Left blue light flashes twice, then right blue light flashes once.  I understand that to be light sequence code 21, but I am not sure exactly what the error code is or what it is telling me.  I thought it was a potentionmeter failure, but if so, not sure which one (it has 4 I believe).

I really just need to know what the code is telling me so I can order a part and fix it.  I have replaced all sorts of things on this unit with parts ordered through the Samurai Repair Man, including heating elements, cooling fans, etc.  If I know what part to order, I can fix it.

Thank you.

I believe it refers to the temp selector.  Coresponding to the oven that has the lights
