Perform the following checks:
•
Test F2 in the Power Supply. Refer to
Testing F2 and F3
in the Electrical Trou-
bleshooting section in Chapter 6.
•
Test for bad Jetstack triac. Refer to
Checking for Shorted and Leaky Triacs
in
the Electrical Troubleshooting section in Chapter 6, General Troubleshooting.
•
Test for shorts to Earth. Measure the resistance of
P/JAC2
Pin 1 to Pin 7. It
should be greater than 2 Megaohms.
Are F2 and the triacs OK, and is
P/JAC2
Pin 1 to Pin 7 greater than 2 Megao-
hms? (Ensure your DMM is rated to measure high-impedance resistance.)
