Having to manually defrost an automatic defrost system tells me there is a problem with your defrost timer. Most Beverage-air freezers have a Paragon timer. There are two dials on these timers. An inner and outer dial. On the inner dial is an arrow to indicate the direction of rotation as counter clock wise. On the inner dial is a copper pointer indicating duration of the defrost cycle.

Observe the copper pointer, no movement indicates that the timer is bad.

Hello;

My name is Peter. I am a retired field service refrigeration technician.

I am going to assume your compressor and condenser fan is running. Your condenser fan is in the lower back of your freezer.

You will need to remove the back cover in your freezer. There are 6 screws holding it on.

Check the following (Cover Removed):

1.) Frozen Drain - Your freezer goes into a defrost mode every 8-10 hours, where your freezer shuts down except for the lights, and your defrost heater turns on for about 20-30 minutes to defrost your cooling coil. If you have a frozen drain, the condensate builds up behind the back wall and icing the cooling coil, restricting air flow. You must defrost the coil.

2.) Freezer Fan Motor Failure - Having removed the back wall observe if the freezer fan motor is running. If not replace.

3.) Refrigerant Restriction or Leak - If you observe a large build-up of ice in the upper right hand corner, then you have a restriction or leak. The cost of repair would be about $400.00

4.) Bad Thermostat - In the upper right hand corner of you cooling coil, attached is your thermostat. They can explode, where the back of the thermostat will raise up.

You can also check it with a multi-meter, set to the lowest Ohms (Omega Symbol). You need to cut the wires, leaving enough wire length to rewire back in. Put the thermostat in a glass of ice water for 10 minutes. After, it should Ohm out around 16. It is reads '0' or infinity it is bad. Below 15 or 16 it is bad

How lpw of a temp. Can this freezer reach..and and if only 0 degree could the thermostat temp control be changed out so it could reach les than 0 temperatures like negative 20 or so?


There are different models made for holding different products. Yours has a 1/3 hp compressor for above 20 degs. It may have 0 on the thermostat and may well pull down that far, but -20 would be out of it's reach. Where as it's sister model is made to freeze to below zero has a 3/4 hp compressor. Larger compressor for the lower temps.

Freezer only 33 degrees


The inside temperature should be -18 deg if it is -33 I would suspect it is running constantly, this indicates a faulty thermostat

Have defrosted my 210 cu.ft. upright freezer v2003rw3, do not have my manual to hand . At what setting on the dial should I put it at to start it up?


Every Refrigerator has its own "personality" There is no common
setting for any one refrigerator. I would start with 3
The real solution is what I have always told my customers
Get a refrigerator thermometer and a freezer thermometer
Refrigerator temp should be about 33-37 degrees.
Freezer should be about 0-10 degrees. below 0 is overkill

If this was helpful please rate me.

Whirlpool AFB126/H/AL Freezer - Defrosting & Refrosting


Hi. I am Kelly and welcome to FixYa. Here is the real question..... Is the food staying frozen?

Freezers usually defrost 3 times a day (8 hr intervals) Some as often as 4 times a day. The freezer use concept is that it is not opened more than 3 times a day. (Yes there will be more times than that any given week)

Having said all of that.... some things to look at.

1. Check the door seal for any signs of tears... grease... collapse...

2. Make sure there are no gaps in the door or between the closed door and the seal.

3. Many people don't check this one... but make sure it is level. An un-level freezer can cause the door seal not to function correctly.

Now if your saying that the food is actually defrosting... then there are a few other things that can cause that.

A. Sticking / defective Defrost timer

B. Defrost element is not heating and the freezer goes through a VERY long defrost cycle as the contents have to reach 60 Deg F for the 60 Deg bi-metal thermostat to close and advance the defrost timer to start the compressor.

C. Intermittent operation of the 60 Deg thermostat

I hope this clears things up a bit for you.

Thanks for using FixYa.

Food thawed, freezer running. I moved packages from in front of air ways and turned thermostat to coldest setting & it didn't change anything, freezer still at 32-33 degrees. help


If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air
check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

Evap fan will not come on,jumped out the fan control fan comes on


Since this is a freezer, it should have a defrost terminator/ fan delay. This could have gone bad or you may have a refrigeration problem. Such as low on freon due to a leak. Need more info, I'll explain in detail. Let me know. Will Be more than happy to.

Unit not freezing , evaporator fan wont run


If this is a Bev-Air, don't think the door switch will control the fan. At the evap, there is a temp sensor called a fan delay. When unit goes into defrost mode, this warms up. Some also serve a dual purpose. It will terminate the defrost cycle at a certain temp., say 51 degrees or so, at the evap. Anyway, when unit comes out of defrost, it keeps the fan off so it allows the evap to cool quicker and to prevent circulating warm air. This could be your problem. Not a hard fix but they can be a pain sometimes. Outside chance that the unit is low on refrigerant (freon). This will not let the evap get cold enough to trip the sensor back into position to turn the fan on. Good Luck. Restaurant Parts and More carry alot of Bev-Air stuff. 1-888-814-1110. Ask for Rick
