Rheem HVAC Error Code 30: How to Fix It

Q: What does Rheem error code 30 mean?

It means the compressor's Locked Rotor Amps (LRA) have been exceeded. This indicates excessive current draw, often due to a failing capacitor, hard start, or bad compressor.

Q: Can I reset Rheem error code 30?

Yes, you can clear the error by turning off power to the unit for 30 seconds and then restoring it. However, if the underlying issue is not fixed, the error will return.

Q: Will a hard start kit fix error code 30?

Often yes. A hard start kit provides extra starting torque and helps reduce inrush current. It's a common fix for LRA errors.

Q: How do I test a Rheem compressor for LRA?

Use a clamp meter to measure the compressor's starting and running amps. Compare to the LRA rating on the compressor's nameplate. If amps exceed LRA, the compressor may be faulty.

Q: Is error code 30 dangerous?

It can indicate a serious electrical problem. High current draw can damage components or cause a fire. Always turn off power before inspecting.

Abstract

Rheem HVAC error code 30 indicates that the compressor's Locked Rotor Amps (LRA) have been exceeded. This usually means the compressor is drawing too much current, often due to a hard start, electrical issue, or mechanical binding. Follow these steps to safely diagnose and resolve the problem.
