Diagnostics
11-7) No defrosting
Pre-check
1. Although both F R-defrost sensors have short-circuit, a normal operation continues
without a defrost cycle (Refer to self - diagnostics function)
2. When the temperature fuse is open, there is no heating and a defrost occurs naturally by
the compartment temperature increase and eventually, it will cause a blinking of
temperature.
3. When both F R-defrost sensors are open, heating does not end. The compressor remains
off and a temperature fuse will be open. (Refer to self-diagnostics function.)
