Frequently Asked Questions
Does the compressor come with a start relay and overload?
Start and protection components depend on the model and are often sold separately. Check the electrical components listed for the AJ4492Y-XD1A in Tecumseh's data and order the matching relay, overload and capacitor kits if your old parts are worn.
Can I use it on a different refrigerant?
Only on the refrigerants it is rated for: R-134a. Using any other refrigerant can damage the compressor and void the warranty.
What should I do before installing it?
Find out why the old compressor failed, replace the filter drier, pull a deep vacuum and charge by weight to the equipment's nameplate.
