Objectionable odors can develop in refrigerators and freezers.
This happens when food is left too long or is improperly packaged, the drip pan near the condenser at the base of the refrigerator needs cleaning, or the refrigerator is turned off and the door is closed. Warning lights show high temperatures or power failure. Temperature controls do not work. These odors can be difficult to remove. Insulation absorbs some of the odor and sometimes makes removal impossible.
