9.7 Measuring Heatless Dryer Solenoid Voltage
With the Compressor running
:
9.7.1
Locate the Heatless Dryer
Cycle Timer.
The timer has three (3) sets of
terminals (from left-to-right):
“
VALVE
” – Left solenoid
“
IN
” – Incoming power
“
VALVE
” – Right solenoid
9.7.2
Use a Voltmeter to measure
the DC voltage across each
set of “
VALVE
” terminals.
Continue to measure for up to
45 seconds if no voltage is
initially measured.
The voltage should measure
53 Volts DC for 110V units and 106VDC for 240V
units
.
If the voltage is incorrect, this is an indication that the Cycle Timer is defective
and should be replaced. See sections 11.3 for part detail and 11.5 for ordering
information.
