Get an EEV Open (Like Magic)


This tech tip comes from our contributor, compressor decapitator, and super tech Ulises Palacios.

Many ductless systems and some high-efficiency unitary systems have electronic expansion valves.

If you find one that is stuck closed, you may be able to get it open temporarily by putting a strong magnet like the one shown above on the valve body and turning it counterclockwise.

This is likely only temporary, so valve replacement is still needed. However, it can help get the customer's equipment running while you wait to get a new valve.

Pretty cool, Ulises.
