Question about Master Bilt Commercial Freezer DD-66CG

1 Answer

We have a Master-Bilt DC8 Ice Cream Storage freezer. It starts gradually warming about three weeks after we defrost it. Defrosting fixes it for a short time. We've had a repairman who replaced a part and added refrigerant but the problem still persists. Any suggestions?

Hi, It sounds to as though you may have a small refrigerant leak in the system. I wish I knew the part he replaced, it must have been in the refrigerant circuit to have to add freon, or it was low in the beginning. They are sealed systems and only require freon if they develop a leak. I think what I would recommend at this point is for them to check the charge again. If it is low, by E.P.A. law's, they need to add dye to locate and repair leaks the second time around, if it is low only. Maybe you can let me know what part was replaced, that would be somewhat helpful.
PS How are you defrosting this box? Most low temperature boxes have a defrost clock on them. Yours may not.

Needs a new defrost timer. If ice builds up then you are not defrosting. If you are not defrosting then the t-stat will read the ice and think it is down to temp and shut off.

The freezer works fine, but it ices up on the inside.

If the ice is clear and hard, the issue is a leak during defrost (if it has such a cycle)

If the ice looks like snow, replace the door gasket(s).

Everything in our freezer is frozen solid except for the ice cream which is soft and mushy, the freezer is only about 3-4 years old and we checked and it is turned up to the coldest setting, any ideas what...

If this is a self defrosting model make sure that you don't have frost build up on the back wall of the freezer causing the air not to circulate like it should. If you do have frost build up other items will eventually start thawing as well. If this is the case you have a defrost problem.

If this is not a self defrosting model then make sure it does not need defrosting.

You normally will notice ice cream being soft before you notice other things thawing.

Also make sure the door is shutting good and you may try putting the ice cream in a different location.

Walk In Freezer won't start up

It sounds like your drain heater is the type that should be deadended. Power makes the circuit between the material it is made of. It is to just be warm, not hot. I've not seen this in some time but that's how they used to work.
Generally speaking, walk-in freezers have bunches of controls.

go to this web site as it will cover the M series unit. Do this first and if you are still having a problem, get back to me.

I have the same problem

Most probably defrost thermostat is defective. Unit never goes into defrost, ice forms on coil and in floor of freezer. After defrosting may work OK for a week or two but gradually gets warmer because ice is blocking ports where cool air gets to refrig. May also have water in refrig box. Can also be caused by defective defrost timer. This can also be caused by the drain hole being blocked by ice. You MUST remove all ice in drain under freezer coil. Use turkey baster to squirt hot water into hole and use hairdryer to defrost.

Hi, Are you seeing ice or frost? Is frost building up on the freezer back wall? I can help you, just need to be clear.

Upright freezer

sounds like your freezer isn't maintaining a constant (cold) temp. A variation from cold to warm would cause your problems. Normal opening the door and looking for the ice cream over and over would cause a gradual increase in glacier activity in the freezer. I don't know of any quick easy fix-but wait, how about checking the door gasket? Get a piece of paper, close the door on it, move the paper all around the door, testing to see if you can pull it out easily (bad gasket), or does the paper not want to come out?(good gasket) If the gasket seems ok, it may be time to retire the global ice cream warming freezer countrycurt0
