Why will my frig not do it's defrost cycle? Could it be the temp Fuse - where is it?


First off try taking a vacuum cleaner and cleaning off your coils of any dust, dirt or hair that is blocking good air flow to make sure your refrigerant is as cool as possible before it hits the compressor.

If you have frost on your evaporator coils that means the coils probably are covered in an ice layer which stops the coils from absorbing heat from your refrigerator because believe it or not, 32 F ice is not near as cold as evaporator tubes with refrigerant running thru them at about -20F or lower.
So make sure there is a nice unobstructed air flow to condensing coils and fan so the heat from refrigerator compressor can be carried away properly.

After everything is really clean, turn refrigerator completely off for the night to make sure any ice formed on the coils is melted away. Any ice on the coils will screw up the thermostats and then the refrigerator will turn on the compressor to run even when it shouldn't

So do a complete manual defrost before going back on

My refrigerator is cool but not cold. My freezer is keeping things frozen but takes longer to form ice (no ice maker) and my ice cream is soft. I hear the motor running and I do not have any frost build...


Hi Nancy,

I bet you've got all kinds of frost / ice behind the plastic cover that protects (and shields from view) the cooling coil in the freezer compartment.

You probably have one or more: defrost timer, defrost terminator or defrost heating element that has failed. Call for service - or empty the fridge and unplug with door open for a day - ice will melt and when you plug in again it will work just fine. Until frost builds up again that is.

Good luck!

Westinghouse Heavy Duty 25 Dehumidifier frost on coils


MIKE - I have the same problem...previously, there was NEVER any frost, and the unit worked just fine. Now, all of a sudden in the last week, frost has been forming...water no longer traverses thru the tube into the sink...and the unit is basically useless/

I think when the original person said "frost", they meant ICE!

Freezer too dry


Why is this question in camcorders?

Water can evaporate from ice. This is called "sublimation".

As a result, ice cubes shrink, especially in frost-free refrigerators, which are often very dry. Frost free models have a fan that circulates air internally so the moist air gets blown out, rather than

Freezers get condensation from moist air that gets inside when you open the door. Frost free models cycle off every few hours, and warm up a bit (a heating coil) to melt the condensation and then they blow that out so it won't form frost. They also blow out any vapour from the sublimating ice cubes. Then they cool down again.

Why is my ge refriderator "frost-free" freezer frosting up?


most likely the defrost heater behind the panel thats frosted up is burned out so it cant defrost the unit,g.e. is notorious for this,remove this panel inside the freezer and remove 2 screws at the bottom of the evaporator coil holding the heater to the evaporator and unplug it the new part number is g.e. WR51X10055

Freezer compartment has frost buildup


This can be caused by the drain hole below freezer coil 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. Possible 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.

My cooper line outside on my air conditioner keeps freezing over causing my ac to blow warm air instead of cold air


The evaporator coil that is low pressure and low temperature needs an adequate supply of heat to absorb from air passing over the fins or a thin dusting of frost will begin to form further insulating the coil from the passing air and causing more ice to form. First you have to get rid of all the ice by allowing the coil to thaw you can use a heat gun or hairdryer or lamp to speed the thawing but the fins and copper tubing are thin and easily damaged so don't use tools on the coil to remove ice. After thawed the coil needs to be cleaned with an indoor evaporator cleaner ( I also use a small shopvac and nylon brush) Then be sure that the filter is clean and the blower is functioning properly then if the suction line is still frosting you will have to verify that the size of the outdoor section is not over sized in relation to the evaporator coil and that the system is charged to meet the compressors manufactures specifications.
