AC Electrical Repair (Capacitor & Wiring)

AC humming but not cooling? Don't force it to run! A SAR 150 capacitor replacement now can save you from a SAR 2,000 compressor replacement later. We diagnose and fix electrical faults safely in Riyadh.

Signs of Electrical Failure

🔊

Humming / Buzzing

The outdoor unit makes a loud "Hummmm" sound, but the fan isn't spinning. This usually means the Capacitor is dead and can't jump-start the motor.

Tripping Breaker

The AC switch in your room trips immediately when the compressor tries to start. This indicates a Short Circuit or a grounded compressor.

🔥

Burning Smell

A plastic/rubber burning smell from the AC vent means wires are melting or a terminal block has burnt out due to loose connections.

⚠️

Danger: High Voltage!

AC capacitors hold a lethal electrical charge even when the power is off. Never attempt DIY repair. Our technicians use insulated tools and discharge equipment to work safely.

🔧 What We Fix & Replace

We carry universal parts in our vans to fix 90% of electrical issues on the spot.

🔋
Dual Run Capacitor
The "battery" that starts your compressor. We replace weak capacitors (e.g., 45µF, 50µF) with high-quality, heat-resistant ones.
🧲
Contactor (Relay)
The switch that sends power to the outdoor unit. If it's pitted or burnt (causing buzzing), we install a new heavy-duty contactor.
🔌
Burnt Wiring/Terminals
Riyadh's heat causes wires to become brittle. We cut out burnt sections, install new high-gauge wires, and replace melted terminal blocks.
🚀
Hard Start Kit
For older ACs that struggle to start, we install a "Hard Start Kit" to give the compressor an extra boost and extend its life.

F.A.T. (Functional Acceptance Test)

We verify the repair with precise measurements.

1. Amp Draw Measurement
After replacing the part, we use a Clamp Meter to measure the Amperage (Current). It must match the "RLA" (Rated Load Amps) on the manufacturer's sticker. If it's too high, the compressor is under stress.
2. Short-Cycle Test
We turn the AC off and on again (with a delay) to ensure the capacitor can reliably start the compressor multiple times without failure.
3. Voltage Stability Check
We check the voltage at the outdoor unit terminals. Loose connections cause voltage drops which overheat the motor. We tighten everything to ensure stable 220V/230V.
FAQ: How much does a capacitor cost?
A standard capacitor replacement typically costs between SAR 150 - SAR 250 (including part and labor), depending on the AC size (tonnage).
