20 Most Recent Delfield Freezer 6151XLSR Stainless steel Questions & Answers

The problem you describe is not very frequent but happent also before. The breaker trips either from oveload and this when the compressor motor find it hard to start up and the second reason from an electrical earth leak from a power point which is again compressor, fan motor and defrost heater. Manytimes everything look to work fine but leak oroverload happens periodicaly and from previus experiance the only way to identify problem is not can be done by just one or two hour visit of a technician but a longtime supervision in a workshop or from owner. This can happent by doing something else in the same room with fridge in order be able to identify if the breaker goes off during a defrost then is the defrost heater, during copressor starting thenis the compressor or compressor starting device or one of fan motors evaporator motor or condenser motor.
As you may understant this is one not easy problem since it only occur periodicaly but with full supervision can be identify especialy from an experience percon and there is not any other option.

If there is ice on the compressor that means that the freezer does not go through any defrost, probubally for a wile now. Best thing to do is tun it off for a couple hours then back on. The ice isn't going to hurt the compressor unless your house is very cold. But you will need to fix your defrost problem.

Does the plug prongs look like the prongs on your hair blower?

Defrost limit/fan delay switch may be bad however if the coil temperature is not 25* the switch will not close.

I would look to see if it is tripping during the defrost cycle. One of the heater elements my be faulty. Never heard of a bad TXV causing a breaker tripping, but I guess it's possible. I would adjust the superheat so that it is about 6 to 8 degrees just prior to unit reaching temp and shutting off. I'd start there.

There is definately a ground fault in this unit. Also according to the service manual this is an "Electronic Defrost Control" similar to an "
Adaptive Defrost Control" which determins the defrost initiation by the amount of run time. You cannot set this yourself.

The breaker must be worn out or the wires to it are loose. With the power off tighten them and see how it does. You can switch to another breaker to see if that's the problem.

Check the defrost heater, sounds like it is burnt out allowing ice to build up therefore restricting cold air flow. Then the freezer warms up, ice melts and it starts freezing again.

from what their web site shows, all of their gaskets are some sort of push in (Dart type) or clip in on a strip. Removing the inner panel is not necessary.

Take a hair dryer (or take off the gasket and throw them in the clothes dryer (yes I am for real I do this all day long)) then put them back on. or the hair dyer way is keep heating the gasket up and holding the door closed while you do it. they should start to seal as you are pressing them together.

Try it in a normal plug. Freezers and refridgerators just pull too much to be used on a GFCI. The more a GFCI is used the eaiser it trips.
