Material, fuel, labor, everything has gone up. Even if you don’t want to raise prices, eventually you have to or margins disappear.

Most systems are designed around 0.5 or lower, once you get that high you’re starving the coil and everything shifts superheat climbs, suction drops, and it sends you down the wrong path.

It only flipped for a second, but even that’s enough to create a real hazard if there was an actual event.
Everything points to an override or priority conflict somewhere in the fire sequence logic that needs sorting out.

No obvious leaks, and refrigerant charge looks correct.

Could this be a TXV issue, or something else deeper in the system? Anyone experienced similar behavior and figured out the root cause?
