⛔ Diagnosis

AC Won't Respond — Start With the Simplest Causes

Check the circuit breaker first: Go to your electrical panel and confirm the AC breaker is ON. If tripped, reset it once only.
Try the manual panel: Most units have a direct power button. If it starts without the remote, the problem is the remote only.
Replace the remote batteries: More common than you think — dead batteries cause apparent "AC failure."
Wait 15 minutes: The compressor may have triggered thermal protection lockout. Switch off at the mains isolator and wait.

💡 If you hear repeated humming or smell burning, isolate from the mains immediately and contact us.
