Possible Causes

Tripped circuit breaker supplying Camry AC, Blown internal fuse on indoor PCB, Loose live/neutral connection at indoor terminal block, Faulty indoor main control PCB

How to Fix / Troubleshooting

Safety first: Before opening any panels, switch off the breaker feeding the air conditioner.

  • 1. Check household breaker: Locate the breaker labeled for the Camry air conditioner and reset it if tripped. If it trips again immediately, do not force it on.
  • 2. Verify wall isolator: If there is an external isolator switch near the outdoor unit, ensure it is in the ON position.
  • 3. Inspect indoor terminal block: Remove the indoor front cover and check that L, N, and Earth wires are firmly secured and not burnt.
  • 4. Check indoor PCB fuse: Many Camry indoor boards have a small glass or cartridge fuse. If blown, investigate for shorts before replacing with the same rating.
  • 5. PCB replacement: If power is present at the terminal block but the board is dead, the indoor PCB may need replacement by a technician.
