Component
Test Procedure
Check result
Remark
1. Thermal cut off
• Check Top Marking:
N130
Measure resistance of terminal
to terminal
①
Open at 266 ± 12°F
(130 ± 7°C)
②
Auto reset 31°F (35°C)
Same shape as Outlet Thermostat.
If thermal fuse is open must
be replaced
①
Resistance value
≒
∞
②
Continuity (250°F
↓
) < 1
Ω
• Heater case-
Safety
• Electric type
2. Hi limit Thermostat
(Auto reset)
Measure resistance of terminal
to terminal
①
Open at 257 ± 9°F
(125 ± 5°C)
②
Close at 221 ± 9°F
(105 ± 5°C)
①
Resistance value
≒
∞
②
Resistance value < 5
Ω
• Heater case -
Hi limit
• Electric type
3. Outlet Thermostat
( Auto reset)
• Check Top Marking:
N85
Measure resistance of terminal
to terminal
①
Open at 185 ± 9°F
(85 ± 5°C)
②
Close at 149 ± 9°F
(65 ± 5°C)
Same shape as Thermal cut off.
①
Resistance value
≒
∞
②
Resistance value < 5
Ω
• Blow housing -
Safety
• Electric type
6. Idler switch
Measure resistance of the
following terminal:
COM - NC
1. lever open
①
Resistance value < 1
Ω
2. Lever push (close)
②
Resistance value
≒
∞
5. Door switch
Measure resistance of the
following terminal
1) Door switch knob: open
①
Terminal: COM - NC (1-3)
②
Terminal: COM - NO (1-2)
2) Door switch push: push
①
Terminal: COM - NC (1-3)
②
Terminal: COM - NO (1-2)
①
Resistance value < 1
Ω
②
Resistance value
≒
∞
①
Resistance value
≒
∞
②
Resistance value < 1
Ω
If the knob is
pressed, the
state is the
opposite of
what is on the
chart.
WARNING
• When checking the Component, be sure to turn the power off, and do voltage discharge sufficiently.
•
Failure to follow these instructions can result in death or electrical shock.
