Valves or PCB Board Problem
by: Hintech

Hi Mr Lee,

Thank you for your submission.

From the description you provided...

There are 2 possibility, the valves which supply freon might be faulty. This problem causes the freon to send to wrong indoor fan coil.

Another possibility is that the outdoor PCB might be faulty which sends wrong signal to the wrong indoor fan coil.

When freon is supply to your living room air-con which is not switched. Ice will starts to form on the coil and when the compressor is off, the ice will starts to melt. To prevent it from happen, switched ON your living air-con too when you feel that it is cold.

There might be more than 2 possibility which are mention above. You might still need a air-con technician to have a look at your air-conditioner.

If you need our service, please give us a call at 96192088. We charge $45.00 for troubleshoot of air-conditioner. Parts replacement is charge separately.
