Description
The York S1-025-33326-000 is an OEM-quality insertion-type crankcase heater engineered to protect compressors from refrigerant migration during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this heater prevents liquid refrigerant from mixing with compressor oil — a leading cause of compressor failure on startup.
Key Features
- Insertion-type design for direct installation into the compressor crankcase
- Wide voltage compatibility: 100–600 Volts, suitable for a broad range of commercial and residential HVAC systems
- 30-Watt heating output for efficient, low-energy crankcase protection
- 3/4″ diameter heater element for a secure, reliable fit
- 1-1/4″ insertion length for proper thermal contact within the crankcase
- 48″ lead wires for flexible installation and easy routing to the power source
- Genuine York OEM replacement part — SKU S1-025-33326-000
Why Crankcase Heaters Matter
Refrigerant migration into compressor oil during the off cycle can cause catastrophic bearing and valve damage on startup. Installing a properly rated crankcase heater is one of the most cost-effective ways to extend compressor life and reduce service calls.
