Lennox 93G35 Thermostat/Freeze

The Lennox 93G35 Thermostat/Freeze is a critical OEM replacement part (identical to Lennox 93G3501) designed specifically for freeze protection within high-performance HVAC systems. This FreezeStat kit is essential for preventing structural damage to the indoor coil and piping. It features a precise operating set point where the switch opens at 29°F (-2°C) to cycle the compressor off, protecting the system from freezing conditions, and closes once the temperature rises to 58°F (14°C) to resume normal operation. Built for durability, this 3/8-inch suction line thermostat is frequently utilized in low ambient kits and is compatible with various Lennox residential and commercial units, including the 13ACX and CHA16 series. For veteran contractors, the 93G3501 freeze stat provides reliable coil temperature monitoring, ensuring your equipment maintains thermal integrity during extreme cooling demands or low-load conditions. The 36.5-inch lead length allows for flexible installation near the suction manifold where accurate sensing is paramount for system freeze prevention.

• System Safeguard: Actively prevents indoor coil icing by cycling the compressor off at 29°F, mitigating the risk of HVAC freeze damage.
• Precise Reset Logic: Automatic reset at 58°F ensures the system returns to service only after the hazard has cleared.
• OEM Compatibility: Serving as a direct replacement for Lennox 93G3501, this unit integrates seamlessly with 24V AC control circuits.
• Robust Industrial Design: Engineered to withstand the thermal cycling typical of low ambient applications and evaporator line mounting.

Where should the freeze stat be installed for the best response time?
For maximum sensing accuracy, install the Lennox 93G35 on the copper exit line of the indoor coil, specifically between the last hairpin and the suction manifold.

Is the 93G35 compatible with R-410A systems?
Yes, this freeze thermostat is standard for HFC-410A refrigerant applications where high-pressure and low-temperature monitoring is required.

Can this part be used in place of the 93G3501?
Confirmed. The 93G35 and 93G3501 are functionally identical and share the same technical specifications for HVAC temperature control.
