Most problems can be diagnosed visually:
1 - cracked end cap covers
Fix: replace and use Scotch 33 (or 88) tape to protect from uV
some people put small drain holes on the bottom side
to supplement the holes in the trap cover
2 - Loose trap cover screw
Remove and inspect insides, then retighten.
You may need to go to a larger screw to get a tight fit
3 - Loose screw(s) on the coils
Clean the connection and retighten. Clean coil wire.
4 - Debris and / or insect nests inside traps
Clean out
Note: Disassembly can be difficult if the dimples hold the
inner plastic spacers too tightly. They 'should'
come apart with some 'persuasion'...
