Hakko FX-951 Errors
« on: November 13, 2016, 04:31:04 am »
Greetings,

I have a Hakko Fx-951 thats started throwing S - E  errors.


I followed troubleshooting, and the manual says its an issue with the hand iron basically, but I have tried 2 other known good FM-2027 irons. Same issue.

I cant find any schematics for the 951 or any troubleshooting for this type of issue.

I'd still recommend you contact them as they've been helpful to others in the past IIRC, particularly as they don't actively publish their schematics.  ;)

Can't hurt at any rate.  ;D
