OPERATING INSTRUCTIONS 
 

AUTOMATIC TEMPERATURE CONTROL – The control is pre-set to maintain the ideal 
temperature of this appliance.
 If necessary, temperature can be adjusted using minimal increments. 
 

MFB-0920: The temperature control is located in the “hood” directly above the door 
MFB-2020: The temperature control is located on right side wall inside cabinet 
MFB-2920: The temperature control is located behind the louvered grill at the bottom of unit 
MFB-2030: The digital temperature control is factory preset and is not adjustable 

 
A.  DEFROSTING-This is a manual defrost system.  If ice build up is present ¼ inch or more on the 

fixed shelves, defrosting is recommended.  Large ice build-up will reduce cooling efficiency.  

 
B. CLEANING 

1.  Cabinet Exterior – Wash with a mild soap and water solution.  Rinse with clear water and dry. 
2.  Cabinet Interior – Wash with 2 tbls. of baking soda and 1 qt. warm water solution or mild soap. 
 
DO NOT USE STRONG CLEANERS, SCOURING POWDER OR PADS. 

 
 

COMPRESSOR – CONDENSER 

 

The compressor is hermetically sealed and will require no attention.  The condenser is located 
between the inside and outside walls of the freezer and also requires no attention.  Its natural heat 
keeps the exterior free of moisture; because of this, the outside may feel warm to the touch.  This 
condition entirely normal. 

 

 

SERVICE 
 

In the event this freezer does not operate properly, check the following before calling the service man: 

1.  Is there adequate air circulation around the unit and in the room? 
2.  Is electrical power reaching the unit?  (Check for blown fuse or “tripped” breaker.) 
3.  Is service cord connected to outlet? 
4.  Is door closed tightly? 

If this does not correct the problem, contact a competent service technician.
