Power Choke (L13)
A choke coil is used on G61MPV 5 ton 1 hp units. The
choke is located on the blower housing and is used to sup-
press transient current spikes.
Precautions
If the G61MPV or its electronically controlled blower motor is
improperly or inadequately grounded, it may cause television
interference (commonly known as RFI or radio frequency in-
terference).
This interference is caused by internal switching fre-
quencies of the motor controller. TV interference may
show up as small specks or lines which randomly appear
on the TV screen accompanied by pops or clicks in the sound.
Before attempting any service, make sure the indoor unit is
causing the interference. To check, disconnect power to indoor
unit then check TV for continued signs of interference.
TV interference may be stopped by making sure the mo-
tor is solidly grounded to the cabinet (metal to metal) and
by making sure the cabinet is solidly grounded. If TV in-
terference persists, make sure the television (and all af-
fected RF appliances) are moved away from the G61MPV.
Also make sure affected appliances are connected to a sepa-
rate electrical circuit.
