Thermostat for Freezer No name model 077B2640 (MPN Czę002301) — mechanical temperature control

Replacement mechanical thermostat designed for freezers, identified as model 077B2640 from No name. This thermostat provides manual temperature regulation for freezer units that use a conventional mechanical control element. It is intended for repair or maintenance of compatible freezers to restore or maintain the ability to set and hold the required internal temperature for frozen goods and safe storage.

Advantages

The mechanical thermostat offers a simple, reliable method of temperature control without electronic components, making it less sensitive to power surges and electronic failures. Its design supports straightforward installation into systems built for a standard mechanical control, and it enables direct, tactile adjustment of the setpoint. The lack of complex circuitry reduces replacement cost and simplifies troubleshooting when diagnosing cooling issues.

Suitable for

• Repairing household or commercial freezers that use mechanical thermostats
• Replacing a faulty or worn mechanical temperature control in older refrigeration units
• Maintenance tasks requiring a direct, manual temperature adjustment mechanism

Key specifications

• Type: mechanical thermostat for freezer applications
• Control method: manual dial or lever for setpoint adjustment
• Function: temperature regulation and on/off control of compressor circuit
• Compatibility: intended for freezers designed to accept standard mechanical control elements
• Construction: sealed mechanical sensing element and switch suitable for refrigeration environments

How to use

Turn off power to the freezer and disconnect from the mains before attempting replacement. Remove the access panel to reach the existing thermostat, note wiring positions, and carefully disconnect the wires. Install the replacement thermostat into the mounting location, reconnect wiring according to original terminals, and secure the unit. Restore power and adjust the mechanical dial or lever to the desired setpoint. Allow the freezer to stabilize and verify internal temperature with a thermometer before loading with perishable items.

Usage recommendations

Use this mechanical thermostat in systems designed for mechanical controls; verify electrical compatibility and wiring before installation. After replacement, monitor freezer temperature for 24–48 hours to confirm stable operation and prevent spoilage. If unsure about installation or electrical connections, consult a qualified technician.
