What number should I set the temperature control to?
Answer Hello Lester! Here is the information from the owners manual for your Frigidaire model MFU20F3GW7. Thanks!
-The temperature control should be factory pre-set to number 4, which will provide satisfactory food storage temperatures. However, the temperature control is adjustable to provide a range of temperatures for your personal satisfaction. If a colder temperature is desired, turn temperature control knob to a higher number. Adjust by one numerical increment at a time, and allow several hours for temperatures to stabilize between adjustments.
