RCA freezer runs constantly and is too cold; ice crystals form on food, and ice cream becomes very hard.

Safety first: Unplug the freezer before removing the control housing or thermostat.

Steps to correct overcooling:

• 1. Adjust the control: Turn the temperature control to a warmer setting and listen for the compressor to shut off within a few minutes. If it never shuts off, the control may be stuck.
• 2. Access the thermostat: On mechanical RCA freezers, remove the control knob and screws holding the thermostat housing. Carefully pull out the thermostat.
• 3. Test the thermostat: Disconnect wires and check continuity across the thermostat terminals while turning the shaft. It should open and close as you rotate. If it remains closed regardless of position, replace it.
• 4. Replace the thermostat: Install an RCA-compatible thermostat, routing the sensing bulb in the same location as the original and securing it with clips.
• 5. Reassemble and set the temperature: Reinstall the housing and knob. Set to a mid-range setting and monitor the temperature with a thermometer.

Note: On electronic models, follow the thermistor and control board testing steps described for E1/L1 if overcooling persists.
