Maintain reliable refrigerator performance in cold locations with this genuine OEM heater kit, part 5303918301, designed for select top-mount refrigerators (e.g., Frigidaire / Electrolux models). This garage kit helps ensure your unit senses the correct ambient temperature and continues to cool effectively even when ambient temperatures fall below typical room temperature. According to the manufacturer, it’s “used on all top mounted refrigerators to protect the refrigerator when used in an unheated garage in extremely cold areas.” Amazon+3applianceparts.lowes.com+3frigidaireapplianceparts.com+3

Features & Benefits
-
OEM-engineered heater kit: Specifically designed by Frigidaire/Electrolux to ensure reliable operation of compatible units when installed in low-temperature environments (garages, unheated basements). The Home Depot+1
-
Prevents compressor mis-cycle in cold ambient: Helps avoid the refrigerator falsely sensing high ambient temperature and shutting down or under-cooling, thus preserving food safety and unit longevity.
-
Straightforward installation: Includes heater pad and instructions; compatible with many top-mount refrigerators (however technician verification is recommended). Amazon+1
-
Cost-effective climate upgrade: Instead of replacing the entire refrigerator for garage use, this kit enables your existing unit to perform reliably in colder settings.
Common Symptoms That Indicate Installation Is Needed
-
Refrigerator struggles to maintain proper temperatures when located in a cool or unheated area (garage, shed, second line) especially when ambient drops below ~40 °F.
-
Freezer section seems to get cold enough but fresh-food side fails, or cycling doesn’t seem normal.
-
The unit appears to turn off or go into “warm ambient” control mode when placed in a cooler environment.
-
You are advised in the owner manual that a “garage kit” is required for use below a certain ambient temperature threshold.

Compatibility Notes
-
Confirm your refrigerator’s model number, door/drawer configuration, and that the ambient environment is within manufacturer’s “garage kit” specification (typically below standard ambient operating range).
-
If the unit has had previous modifications, or if it’s located in a severely cold environment (e.g., unheated garage in winter), the heater kit may be necessary for reliable operation.
-
While the heater kit addresses ambient-temperature issues, it does not fix other refrigerator faults such as faulty compressor, coolant leak, electronic control failures or door gasket issues. Have a technician review if you suspect other problems.
-
Installation involves electrical wiring and possibly mechanical fitting; if you’re not comfortable with appliance wiring or modification, hiring a qualified technician is strongly advised.
