5. BLOWER MOTOR AND CONVECTION MOTOR
1) Remove a connector from the motor.
2) Measure resistance between two terminals like as following figure.
3) Reading of blower motor is 60Ω and convection motor is 270Ω .
4) It is normal to stop convection motor smoothly, when door is open during convection mode.
=> You can see the motion of convection motor,
6. HEATER (TOP HEATER, REAR HEATER, HALOGEN HEATER)
1) Remove a connector from the heater
2) Measure resistance between two terminals like as following figure.
3) Normal readings of top heater, rear heater and halogen heater are 36Ω, 36Ω, 23Ω.
4) The oven should be cooled enough to measure resistance of the heater.
7. NOISE FILTER
1) Remove a connector from the noise filter.
2) Check each continuity of N-N and L-L terminal like as following figure.
3) It should be normal to keep continuous continuity.
