Detecting The Problem

Detecting why timer light blinking on Panasonic air conditioner is not that tough. The easiest way to figure out the problem is to check the remote control or your air conditioner. It may have valuable information regarding the problem. However, if you can not find out much, physically check the AC.

For internal error, open the air conditioner. Check if the air conditioner is clean or not. Specially check the filter area. Next, check the evaporator coil, wires, and PCB. Also, check all the connections related to installation. Check if all the connections have been made correctly.

For detecting external issues, check the performance of the thermostat.

  • Correct The Installation Faults: Go for it if you know how to do it. But it is better to let an expert do it.
  • Tighten The Wire Connections: You can reattach the loose wires inside the air conditioner if you have the skills. But do it only if you have the knowledge and are confident that you will not mess it up.
  • Unfreeze The Evaporator Coil: Turn off the compressor if the evaporator coil is frozen. So, the temperature will rise, and the coil will be free from its frozen state.
  • Change The Damaged Parts: If any air conditioner part is damaged, do not hesitate to change it. Like you need to change the PCB if it is not unscathed. It is best to let a mechanic do this task for you.
