blows again, send the unit in for repair.
Is the sensor broken?
Measure the resistance value of the sensor. When the resistance
value is ∞, replace the heater.
Is the heater broken?
Measure the resistance value of the heater. The corr
ect values are approximately: 14Ω (
±10%
100-110V), 17Ω (
±10%
120V), 41Ω (
±10%
220-240V). When the resistance value is not
within the normal range, replace the heater.
The fan may be broken. Replace the fan with a new one.
