To replace the Freon in a Hotpoint refrigerator, braze an access valve to the unit's compressor, and vacuum the compression system using a specialized pump. Determine the type of refrigerant the fridge requires, and add it through a hose attached to the access valve. Finally, add PAG oil.
Before attempting to replace the Freon in a Hotpoint refrigerator, check for oil on the bottom of the unit to determine if a Freon replacement is needed. If the Freon needs to be replaced, add an access valve to the unit's compressor using a T-shaped pipe, and then braze the valve into place. Vacuum the compression system using a specialized vacuum pump.
Next, determine the type of refrigerant required by consulting the fridge instruction manual or the name plate affixed on the side of the unit. Before adding the refrigerant to the Hotpoint unit, attach a hose to the access valve in order to introduce the Freon into the compressor. Finally, add a maximum of 5 tablespoons of PAG oil.
Only replace the Freon in a Hotpoint refrigerator if you have the specialized tools and materials and a permit to legally purchase the refrigerant. Getting a licensed professional to do the job is strongly recommended.
