How to Cross Reference Tecumseh Compressors
Cross referencing involves matching the specifications of the original compressor with an alternative model that offers similar or improved performance. Here’s a step-by-step guide:
Step 1: Gather Essential Compressor Details
Collect the following data from the existing compressor:
- Model number
- Serial number
- Refrigerant type
- Voltage and phase
- Capacity (BTU/hr or tons)
- Physical dimensions and mounting configuration
- Lubrication type (oil type and volume)
- Displacement and compression ratio
Step 2: Consult Manufacturer Resources
Use Tecumseh’s official catalogs, technical manuals, and cross-reference charts to identify compatible models. These resources often include:
- OEM part numbers
- Equivalent models based on specifications
- Compatibility notes for refrigerants and voltages
Step 3: Use Cross Reference Tools and Guides
Several tools can assist in cross referencing, including:
- Online cross-reference databases
- Distributor catalogs
- Technical support from Tecumseh or authorized distributors
Step 4: Verify Compatibility
Ensure the replacement compressor matches:
- Same refrigerant compatibility
- Similar capacity and displacement
- Identical mounting and electrical configurations
- Similar physical dimensions for ease of installation
Step 5: Test and Confirm
Once installed, perform operational tests to verify that the replacement compressor functions correctly within the system.

Common Tecumseh Compressor Cross Reference Charts
Many manufacturers and suppliers provide cross-reference charts for Tecumseh compressors. Below are some key points:
Popular Tecumseh Compressor Series
- Model Series: OS, AE2, AE3, EAL, and more
- Refrigerants Supported: R134a, R404A, R22, R410A, etc.
- Capacities: Ranging from small residential units (~1/12 HP) to large commercial systems (>5 HP)
Sample Cross Reference Approach
Suppose you have a Tecumseh OS-37 compressor. To find a cross reference:
- Check the model number specifications, such as displacement and voltage.
- Identify compatible models with similar specifications, like the Tecumseh AE2-30 or EAL-30.
- Consult cross-reference charts to verify refrigerant compatibility.

Factors to Consider When Cross Referencing Compressors
Accurate cross referencing involves more than matching model numbers. Consider these factors:
Refrigerant Compatibility
Ensure the replacement compressor supports the refrigerant used in your system, especially with evolving environmental regulations phasing out certain refrigerants.
Electrical Specifications
Match voltage, phase, and compressor motor characteristics to avoid electrical issues or system failure.
Physical Dimensions and Mounting
The physical size and mounting configuration should align with the existing system to prevent extensive modifications.
Capacity and Performance
The replacement should provide similar or improved capacity without overloading or underperforming the system.
Lubrication and Oil Type
Compatibility of lubricant type and volume is essential for compressor longevity.
System Compatibility
Ensure all components, such as valves and controls, are compatible with the new compressor.
