We've got the parts, schematics and experience to repair these for you.

Part Number 8111879.

From what we can gather, these were used in a number of machines in the early 2000s, up to around 2005 when they were replaced by the larger style with discrete components instead of the Crydom modules.

They were used in the 950, 1025, 1050, 1055 and 6401 and possibly also in the 1000 and 1000D

We can repair/return yours if you wish to send it to us or we can ship a unit same day and take your core for credit later.

We have brand new, hand built, replacements for these boards, see pic below. We build them here in North America and fully test them before shipping. They include a proof video that they work and a one year warranty. Discounts available to dealers for volume orders of 6 or more. Call me.
