I need a marks on diode 22 and 23 on motor controler board because they are burned. Motor controler board is pacemaster digital p.s.#501009.
I send a pic in attachment.

Thanks

 

Welcome to AAC.

One might guess at suitable replacements and determine orientation for the one that is more burnt, but the best way would be to check a non-defective board. Do you have such access or have you searched on "repair of xxxx". Fill in the model number for your pacemaster.
