Measure the fuse in the PCBA.
a) With the Multimeter function set to “Ω”, pierce one pen pin into the sealing glue and force the pin
contacting onto one end of the fuse, then pierce the other pen pin into the sealing glue and
contacting onto the other end of the fuse.
b) If the value displayed is below 1Ω, the fuse is good. Go on next PCBA MOSFET testing, otherwise
replace the whole PCBA ASSY directly. No separate fuse replacement is allowed.
