No power on the A/C thermostat

Members location is United Arab Emirates.


My ac unit switch does not show any signs of power reaching it. I have attached a picture of the switch.

What could be the causes ?
  • Fuse failure
  • Ac unit on the rooftop switched off ?

There are numerous ac units on the roof. How can one identify which ac unit is for which flat ?

Thank You

Here in the U.S. if you rent it would be the landlord's responsibility to fix your A/C if you rent. Best advice would be because of liability don't try to fix it. Call the landlord or a repairman if you rent.

Do you have a breaker or fuse box? If breaker have you tried resetting the breaker by turning it all the way off then on. If fuses and you don't know how to test just replace.

Welcome to the forms.

This is predominately a North American based site so we use different equipment from you.

That looks like a line voltage fan coil thermostat. That would be connected directly to the air handler in your dwelling unit. You would need to check that for AC line power.
