Possible Causes

Loose high‑current connection causing thermal cutout, Marginal ground fault leakage triggering brief trips, Overheating of Type 2 connector pins, Unstable grid voltage causing repeated undervoltage events

How to Fix / Troubleshooting

Safety first: After an interruption, carefully feel the cable and connector; if they are hot, turn OFF the breaker and let everything cool.

  • Inspect connector pins: Look for discoloration or pitting on the Type 2 pins. Replace the cable if pins are burnt.
  • Check terminal tightness (power OFF): Tighten all output terminals and contactor connections to the specified torque.
  • Monitor pattern: Note whether interruptions correlate with other large loads turning on in the home; if so, consult an electrician about supply stability.

If interruptions continue with a cool connector and solid wiring, internal sensors or the control board may be overly sensitive or defective and should be evaluated by a technician.
