Display did flash for freezer apparently, but it’s not doing that now.
Checked evap coil, covered in only light frost but more than usual. Fan covered in frost too.
Anyone know what the bimetal switch on these evaps are for?
Heater measured at 290ohm resistance, thermal fuse OK, fan operates.
Forced defrost and heater drawing 0.9A, though never really got hot, just tepid.
No fault in diagnostic mode.
I know that the flashing display is normally related to open circuit in the defrost circuit, but heater and fuse good.
Looked up some info and found that likely causes for fault are heater or freezer temp sensor fault.
But still don’t know why the weak defrost and early termination before the coil fully defrosted.
