Surge protector green LED protection light off?

Hello
This TrippLite Isobar Isoblok428 premium surge suppressor with diagnostic LEDs was installed in 2021 on a Whitfield Optima 3 and worked well for approx 5 years. Not only does it have a green LED light to show it has power and the protection circuit light shows it is working but had a fault light that lights up red if the AC outlet phase is reversed or if there is no ground. When either one of these AC outlet wiring errors occur, the fault LED lights up red and the pellet stove control panel can still be damaged!
In this case, when the stove had its annual fall maintenance the protection light was out. This town has had many issues in the past with power outages but not much in the past few years. However power fluctuations could still be there and not noticed. Power fluctuations can still damage very sensotive pellet stove control panels over time which certainly could have happened in this case! After the stove servicing and cleaning it fired up properly.
Here is the delails of what happened inside this surge protector. Does it look like the control panel was saved in this case?
When the protection light on a surge protector (such as an Isobar or similar strip) goes out, it means the internal surge-suppression components—specifically the Metal Oxide Varistors (MOVs)—have worn out or sacrificed themselves after absorbing a power surge or voltage spike. [1, 2]

What This Means

• Surge protection is gone: The device may still pass electricity and work like a basic multi-outlet extension cord, but it no longer protects your plugged-in electronics (like computers, TVs, or audio gear) from future surges.
• It cannot be reset: There is no manual reset button or fix to restore the internal MOVs once they have failed. [1, 2, 3]
