Choke - GE WPRB9250 Technical Service Manual

To remove the electronic control board:
Caution:
• When replacing the control panel, remove the protective coating from the overlay prior to power-
up to prevent electrostatic discharge (ESD) from damaging the new board.
• To prevent electrostatic discharge, ground yourself to the washer cabinet or use an ESD
wristband.
1. Disconnect power to the machine.
2. Place the control panel in service position (see control panel).
3. Disconnect the harness connections, and remove and retain the model selector harness plug for
reassembly.
4. Remove the control panel assembly.
Control EMI Filter
The potential exists for the washer to cause
electronic devices and systems in the vicinity to
experience disruption. To eliminate the likelihood
of disruption, the unit is equipped with a
conductive noise filter. Should interference with
electronic items be reported, suspect a problem
with the filter. The ground wire attached to the
bottom of the filter must have a good connection
for the filter to operate properly. Check to make
certain that the ground wire is connected properly
before replacing the filter.
The filter is accessed by placing the control panel
in the service position.

Choke

The choke is an EMI (electromagnet interference)
filter located in the lower portion of the wiring
harness, close to the inverter. It is designed to
reduce EMI produced by the unit. EMI has the
potential to disrupt the operation of electronic
devices and systems in its vicinity. Should the
customer complain of interference with other
electronic items while the unit is operating, check
to make sure the filter (see Filter section) is
properly grounded. The choke is not a
replaceable part. In the event the choke fails
(open), it is to be bypassed.
