Normal:
*Toast heater
Approx. 95 ohm
(at 20 ~ 30˚C)
Normal: more than 0.5 Mohm
Measure the resistance.
(Multi-meter scale: Rx1)
Check for continuity of the fuse with an
multi-meter.
Measure the resistance with 500V-100M ohm
insulation resistance meter.
NOTE: Make sure heater is fully cooled when tested.
NOTE: If the fuse is blown, check the primary, the secondary, and the monitor
switches, H.V.D. and H.V.C. before replacing the fuse.
If the fuse is blown by improper switch operation replace the defective switch
and the fuse at the same time. Replace just the fuse if the switches operate
normally.
0°C~Approx.110°C Over 110°C
