The 50A65 has only one serviceable part–an automotive
type fuse, which protects the low voltage transformer from
damage if its output is short-circuited. If the fuse has opened
up, remove whatever caused the short circuit and replace the
fuse with only a 3 Amp automotive type fuse. If the fuse is not
the cause of the control’s problem, replace the entire 50A65
control. There are no other user serviceable parts.
Additional jumper wires are included in this package and
should be used if the original wiring does not reach the
control after mounting. Refer to the furnace wiring diagram for
proper connection of the wires.
Some applications may require connection to terminal E33 lo-
cated in the middle of the contol cover. If the control being re-
placed does not have this connection, it is not needed in the
application and connection to terminal E33 is not required.
Trane application - Jumper wire 151-2906 (provided with
control) must be installed on the furnace from R01 to R02 of
the 12-pin connector.
