Lloyd AC Not Functional Repair in Chennai
The system trips, restarts or shuts off on its own and will not run a full cycle.
When a Lloyd split or window air conditioner refuses to run a full cooling cycle, continuously trips the circuit breaker, or shuts off seconds after the outdoor unit engages, it usually points to an electrical overload or control board logic failure. Lloyd ACs utilize specific micro-channel condenser coils and inverter PCB modules that require precise voltage stabilization. In Chennai’s hot and humid environment, sudden voltage drops and short-cycling can trigger protection modes that leave your Lloyd AC completely non-functional.
Common Symptoms- The indoor unit powers on briefly, displays an error code (such as E1 or P4), and shuts down.
- The miniature circuit breaker (MCB) trips immediately when the outdoor compressor attempts to kick in.
- The unit continuously restarts every few minutes without producing any cool air.
- The indoor display lights flash repeatedly while the blower fan and compressor remain inactive.
- Inverter PCB Failure: Dust accumulation and voltage fluctuations in Chennai often damage the Intelligent Power Module (IPM) on the Lloyd outdoor PCB board.
- Faulty Compressor Capacitor or Relays: A degraded run capacitor prevents the compressor motor from starting, drawing peak current that trips the breaker.
- Defective Temperature Sensors: Malfunctioning discharge or room thermistors send incorrect temperature signals, forcing the control board to shut down the unit for safety.
- Overheating Compressor: Clogged outdoor micro-channel fins lead to high head pressure, causing the internal thermal overload protector (TOP) to trip.
- Diagnostic Scan & Sensor Test: Our technicians check resistance values on thermistors and inspect the indoor/outdoor control PCBs for burnout marks or component failures.
- Electrical System Inspection: We measure voltage draw, check MCB ratings, and test the compressor run capacitor and contactor relay.
- PCB Repair or Component Replacement: Damaged IPM modules, capacitors, or relays are repaired or replaced using brand-compatible components.
- Condenser Cleaning & System Reset: We jet-clean the outdoor condenser fins to relieve head pressure and perform a full system controller reset to clear fault codes.

Frequently asked questions
Why does my Lloyd AC trip the circuit breaker every time the cooling starts?
This typically happens when the outdoor compressor draws excessive current due to a blown capacitor, a shorted IPM module on the PCB, or an overheating compressor. A technician must test the electrical load and components to safely isolate the fault.
How much does it cost to fix a non-functional Lloyd AC in Chennai?
The cost depends on the exact root cause, such as replacing a small capacitor versus repairing the inverter PCB board. Janani Cool Care provides an upfront inspection report and price quote before starting any repair work.
How long does it take to diagnose and repair a Lloyd AC that won't stay on?
Most diagnostic checks and standard component replacements (like capacitors or sensors) take about 1 to 2 hours. If the inverter PCB requires detailed board-level chip repair, it may take 24 to 48 hours.
