Mitsubishi Electric PLFY-P32VBM-E [11/24] Troubleshooting

6. Troubleshooting

Range of application

The range of working temperatures for both the indoor and outdoor units of the series Y, R2, Multi-S is as below.

Warning:

If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since there may be a

refrigerant leak. Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.

The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors and

comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated.

Having trouble? Here is the solution. (Unit is operating normally.)

Noise is louder than specifications.

The indoor operation sound level is affected by the acoustics of the

particular room as shown in the following table and will be higher than

the noise specification, which was measured in an echo-free room.

Nothing appears in the wireless remote controller display, the display

is faint, or signals are not received by the indoor unit unless the remote

controller is close.

The batteries are low.

Replace the batteries and press the Reset button.

If nothing appears even after the batteries are replaced, make sure

that the batteries are installed in the correct directions (+, –).

The operation lamp near the receiver for the wireless remote controller

on the indoor unit is flashing.

The self diagnosis function has operated to protect the air conditioner.

Do not attempt to repair this equipment by yourself.

Turn off the power switch immediately and consult your dealer. Be

sure to provide the dealer with the model name.

Warm air blows from the indoor unit intermittently when heating mode is

off or during fan mode.

When another indoor unit is operating in heating mode, the control

valve opens and closes occasionally to maintain stability in the air

conditioning system. This operation will stop after a while.

* If this will cause an undesirable rise in the room temperature in

small rooms, etc., stop the operation of the indoor unit temporarily.
