Green light has not come back on after defrosting only the yellow one. But it is still working

The green light should be a normal running light and the other one, either yellow or red(ish) should be a high temp alarm. Check the contents to make sure they are still reasonablly frozen and if not start finding the cause....Is the condensor fan motor running correctly? Is the condensor coil clean and free from dirt/lint/fuzz which serves to restrict the transfer of heat? Is there an excessive accumulation of ice build up indicating possibly a problem with the automatic defrost cycle?

sounds like a bad defrost terminator or timer wired wrong. won't make temp as the evap is not clear of ice/frost build up. check your wiring diagram for location and operation of terminator.

if you turn the freezer off for some time then on again the red light has to come on as an indicator for high temperature it goes off by itself when the freezer attains the required temperature according to the thermostat settings ,that is the lower the settings the faster the red light goes off. the orange light indicates super cooling and the green light indicates power supply.if you turn the two lights off and the freezer still works without the green light on that means that the bulb for the green light is faulty and you don,t need to worry

Draw fan has failed, temp unreachable over the past cycle of 24hrs, turn your unit off for 24hrs and defrost it, restart and should work fine for a few days, if so, replace fan and defrost element only. Call service tech for this unless you are clued in on this work, not that costly.

I'd let it dry out totally then try it again, some of the electronics may have gotten wet when you defrosted it. Give it a week somewhere warm and dry like a garage. If you didn't attack built up ice in the freezer with a knife while defrosting it it should work after it dries out. Most people end up killing freezers by accidently poking holes in the evap coil while trying to remove built up ice.

the ice cream is the clue,if it goes hard then the temp is too low (ice cream best kept at -18C)
either the defrost is not working or interior temp sensor duff.

two reds and green are the auto max freeze on indecators the reds go off one at a time when unit drops to safe temp mode.also means unit needs defrosting manually when too much ice is present.

Try to unplug it for about 5 minutes, and then plug it back in

could be a possible short in the electrical

Try advancing the defrost timer manually.
