4.2.2 HEATER TESTING
!
WARNING
RISK OF ELECTRICAL SHOCK.
Set a clamp multimeter to read
amperage and clamp around L1,
wire #0 (Figure 13)
Is the amperage reading
less than 1A?
Check power supply for
120V AC (Figure 18)
Is the voltage reading
approximately 120V AC?
Is the nominal voltage
reading approximately
120V AC?
Are the connections to
the junction box, heater,
and thermal cutoff fi rmly
secured?
Contact a certifi ed
electrician to inspect
house wiring
Reconnect any loose
wires
Place positive probe on the HEATER1
and then HEATER2 terminals of the PCB
(Figures 16 &17)
Set multimeter to
read AC voltage
Set multimeter to
read AC voltage
Place positive probe on the AC-L
terminal of the PCB (Figure 15)
Place negative probe on
the AC-N / AC-N1 terminal
of the PCB (Figure 14)
Is the amperage reading
approximately 5-6A?
Cycle through the heat settings
Set heater setting on H2
Set heater setting on H2
Using a clamp multimeter,
clamp around wire #4 then
wire #5 (Figure 19 & 20)
Did both wires read
approximately 5-6A?
Appliance is functioning
accordingly
Is the amperage reading
approximately 10-12A?
Appliance is functioning accordingly
Turn appliance on
Set heater setting on H2
*Keep the negative probe on AC-N / AC-N1
Defective heater
Refer to section 6.6
(Heater, Blower, and
High Limit Switch
Replacement)
Replace PCB
Refer to section 6.2
(Control Board
Replacement)
Check power
supply for 120V AC
(Figure 18)
Replace wire harness
Refer to section 6.7 (Wire
Harness Replacement)

Unplug the appliance
(if hardwired, turn off circuit breaker)
Unplug the appliance
(if hardwired, turn off circuit breaker)
Unplug the appliance
(if hardwired, turn off
circuit breaker)
Unplug the wires from
HEATER1 and HEATER2
terminals on the PCB
Ensure wire connections are fi rmly
connected at the heater/blower
assembly and at the PCB.
Refer to the wiring diagram
Plug in the appliance and press
power button on the control panel (if
hardwired, turn on circuit breaker)
Did both terminals
read approximately
120V AC?
Check continuity of the heater
wire #4 and #5 to neutral
(Figures 21, 22, and 23)
Measure the ohm value of HEATER1 and
HEATER2 by placing the probes on each
side of HEATER1 and HEATER2 terminals
on the heating element (Figures 24 & 25)
Did both heating
elements read 19-20 Ω?
Is there continuity?
