Frequently asked questions
Answers about electrical diagnostics & testing.
What is the difference between troubleshooting and diagnostics?+
Troubleshooting addresses a specific symptom. Diagnostics may involve broader testing when the source is unclear, intermittent or affects multiple parts of the system.
Is the diagnostic fee applied to repairs?+
Yes. When Nexus Pro Services completes the recommended repair, the diagnostic fee is credited toward that work.
How long does diagnostic testing take?+
It depends on the system and the nature of the fault. Some causes are identified quickly; intermittent or concealed conditions may require more investigation.
