Kicker KXM400.2 protect light, but working

[peeby]

So I have this Kicker KXM400.2 protect light, but working fine.

Any ideas?

Does the Light Bar light up?

If the amp is fully functional, check Q21(C807), Q27(C817), ZD10(6.8volt zener) and associated resistors. Look for any signs of moisture, white or green powder deposits.

Everything checks. If I lift RP10 the light goes out.
