My Origo 2500e Electric/Alcohol Stove started acting up last seasonand finally stopped working altogether. Origo US rep wants almost$300 for a replacement control board. I decided to try and fix itmyself.Here are the front and back pics of the control boards:

What address do you want me to send my board to?

Only kidding... We have issues about twice a season with ours.

Nice repair... I'll have to give it a try... what is the source for the new switches?

How did you figure out which switches were bad? My stove may have the same issues, it doesn't work either.

I got the switches from digikey.com. There is a few suppliers out there. The exact replacement switch is a TL1100AF160Q. I instead got the TL1100F160Q, which was in stock, with the only difference being a 0.5 mm difference in size of the actuator top edge.

I took the boards out and tested the switch contacts with a meter. You need to test between the two closest pins on either side of the switch. They are supposed to give a short as soon as the switch clicks. The bad ones did not. You could, however, make them work if you wiggled the actuator quite a bit. This is of course not possible through the key label membrane during actual use. I also made sure that the board actually worked by wiggling the said switches.
