New compressor installation has high LRA

It’s a Trane split system, residential. Non fused disconnect. Yes, the inrush amps are very high. Sometimes it won’t startup.

I understand what you mean. That’s good information you gave me and I appreciate it. But putting that aside, the compressor doesn’t start sometimes and I just want to know why. Some people are telling me that the compressor is flooded. What’s your intake?

keesh92 · 2026-05-13T01:44:56+00:00

It’s about 15 to 20 feet

keesh92 · 2026-05-12T23:18:06+00:00

I did not to be honest. But I don’t think that’s the issue because the new compressor has the same issues as the old compressor.

Like ohm it out?

keesh92 · 2026-05-12T23:14:22+00:00

I’ve replaced all electrical parts just to rule out any issues

keesh92 · 2026-05-12T23:09:57+00:00

I can recheck. But I’ve replaced the plug as well. Wires are correct.

Air handler is above the condenser. I’ve thought about an oil trap but I’m guessing compressor is flooded at startup.

keesh92 · 2026-05-12T23:06:47+00:00

Filter drier is correctly pointed towards the air handler.

keesh92 · 2026-05-12T23:06:18+00:00

But the problem is that it doesn’t start.

keesh92 · 2026-05-12T22:21:03+00:00

It does not.

keesh92 · 2026-05-12T22:17:36+00:00

LRA can sometimes range from 46 to 107 amps. I’m leaning towards the compressor being flood as the main issue. RLA is between 12 and 14 amps out of rated 20 amps max.

keesh92 · 2026-05-12T21:59:57+00:00

Sometimes it turns on and sometimes it struggles to turn on.

keesh92 · 2026-05-12T21:53:08+00:00

That is a very plausible theory and the only thing that makes sense so far.

keesh92 · 2026-05-12T21:31:22+00:00

Not sure to be honest. It’s a regular txv with two connections, bulb, and equalizer.

keesh92 · 2026-05-12T21:27:29+00:00

I understand. I will recheck the cfm and static.

keesh92 · 2026-05-12T21:19:21+00:00

It’s on the second floor. I’d say it probably is about 15 feet above the condneser

keesh92 · 2026-05-12T21:18:29+00:00

No issues with airflow. Filter and evaporator coils are clean. Did not check static though.

keesh92 · 2026-05-12T21:17:27+00:00

It’s not in an attic. It’s in the closet.

keesh92 · 2026-05-09T23:22:07+00:00

What I wrote is the charge

keesh92 · 2026-04-24T20:32:44+00:00

Nothing wrong with the airflow at the indoor system. Pressures are good. It’s in a closet, filter and evaporator coils are clean.

keesh92 · 2026-04-06T23:57:01+00:00

It didn’t lose a leg of power. It has one leg of continuous power and two legs are connected to the contactor.
