6.9 Defrost heater

Rated voltage:AC220-240V

Rated power:250W

6.9.1 Basic parameters

6.9.2 Checking method

6.Circuit and checking

1.Enter compulsory defrost mode,use a multimeter to measure
voltage between label N and label DEF HT on CN2 connector of the
mainboard,if the voltage doesn’t equal to electric supply power,it
means the heater is broken,change it.
2.Check the fuse is well or not,refer to “6.8 Temperature fuse”chapter.
3.Use a multimeter to measure resistance of the heater,if the value
isn’t 212

Ω±5%,

it is broken,change the heater.
