Title: Hakko FX-951 Errors
Post by: cmccul002 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.

Hakko 951 using lm358 for reading sensor value ! You can check lm358 good or bad

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
