Blower Does Not Work!
1• If indicator lights up on keypad
while blower is in high speed,
take voltage reading between
white and black wire connec-
tors:
240 VAC blower: P59 & P43
120 VAC blower: P49 & P43
Your reading should be:
≈
240 VAC for a 240 VAC blower
≈
120 VAC for a 120 VAC blower
2• Replace blower fuse if you do
not get a high enough voltage
reading.
3• Replace board if you still aren't
getting a voltage reading.
(Refer to "How to Replace the
Board" section.)
4• If you do get a good voltage
reading, check if you can restart
blower a few minutes after
being turned off.
Replace blower if it does not
start after cool down period.
5• If blower does start up after
cool down, it's possible that it
is not drawing in enough air.
6• Enlarge the opening to allow
more air into blower.
