Intermittent Clicking Troubleshooting

Intermittent Clicking / Arcing Noise (Every 10–15 Seconds)

This sound is almost always caused by a tiny piece of debris — often a fine pet hair or dust strand — sitting between the ESP plates. It can be microscopic and not visible, so give the filter layers, plus the front and rear vents, a thorough vacuum and strong blow-out. Once the obstruction is cleared, the clicking stops immediately.
