Pentair 100 minimax is not igniting when it should. System

Customer Question

Pentair 100 minimax is not igniting when it should. System has been working fine for a number of years but was not used for about 4 months. Now it won't ignite.

Does this unit have electronic ignition? if so do you hear the pilot arcing (ticking) when you turn it on? do you have a multi-meter?
Customer: replied 2 years ago.
It does have electronic ignition. There is no clicking. I do have a multi-meter but I am not near the unit right now.

Does it sound like the thermal fuse?
Expert:  Rick replied 2 years ago.
Could be any number of things. Near the top of the list is damage from mice chewing on the wiring insulation. Not likely a thermal fuse if this is the first time you've tried firing it up in months and it worked OK before you last shut it down. You'll have to be onsite to trouble shoot this further.
