Setup
Check Check Check Heater Heater Heater Resistance Resistance Resistance
To reduce risk of injury or damage to equipment,
conduct these electrical checks with the main
power switch OFF.
1. Turn main power switch off.
2. Make electrical resistance checks for the
components.
3. Replace any parts whose resistance readings do
not comply with the ranges listed in tables.
Note
Check resistance at ambient room
temperature 63°– 77°F (17°– 25°C).
