If reliability is critical, replace it immediately. Then, if you must, troubleshoot the

Look at at this way: you made the $100 service call and replaced the $2 part.
(Just throwing out numbers here, so please don't hold me to them). Discard
the bad part so nobody will try to resurrect it, ultimately resulting in
another $100 service call.

If customer wants a spare, sell him a new one, $2 plus an (ahem) appropriate markup.

Or let him buy one on eBay.
