TROUBLESHOOTING F50E AIR CLEANERS WITH A W8600E
SOLID STATE PERFORMANCE INDICATOR AND AIR FLOW SWITCH
Fig. 35. Electrical troubleshooting procedure for F50E electronic air cleaners with a
W8600E and solid state air flow switch.
Test Button
The TEST BUTTON is near the bottom of the access door.
When pushed, it shorts from a hot collector plate to ground.
See internal schematic, Fig. 36. The resulting arcing sound
indicates that high voltage is being supplied to the collector.
The solid state power supply controls current flow to the
collector, so the arcing sound is only about half as loud as the
sound on air cleaners with W919-style power supplies. On air
cleaners with a W8600E, the CHECK LED comes on when
the test button is pushed.
Power Supply Problem
CAUTION
Electric Shock Hazard.
Can cause personal injury.
Always turn off power and remove access door before
removing power box or its cover.
