Question about Sewing Machines
Sometimes OK. Usually get LEDs and work light only. No display, no motor function. Power switch is NOT the problem.
Dealer wants $600. for a new main PC board.
Is there somebody out there who can diagnose to component level and just replace the bad part? The controller is an Intel 8051 technology PC board.
The typical rebuild on this board is done by replacing the 22 micor farrad caps. There are 3 or 5 of them depending if it is new or old style. Note: the power to the sew lamp goes straight from the motor to the lamp, the power to the control panel goes from the motor to the main board (base plate) then to the control panel. If you get the LED's on occasion then it is not the transformer or fuses in the base plate but simply the caps. Sometimes you can just scrape off the electrolytic gel that has oozed out of the caps off of their teminals, but replacing them is the best.
A Pfaff dealer can get a core credit for your board if you take it in. You shouldn't have to pay more than $200-$300 for a rebuilt base plate.
