Introduction to Lloyd AC Error E5
The Lloyd AC Error E5 is a dual-meaning diagnostic code depending on your specific AC series. In most Havells and Lloyd models, E5 indicates an Indoor Fan Motor Abnormality. The indoor PCB has detected that the blower motor is either not spinning or is failing to send the correct RPM feedback signal.
However, in some specific Lloyd Inverter AC models, E5 acts as a protection code for Low Refrigerant Gas. If the system runs but the indoor coil temperature drops dangerously low (indicating a freeze-up due to lack of freon), the system will shut down and display E5 to protect the compressor from dry-running.
Step-by-Step Diagnostic Procedure
Step 1: The Mechanical Blower Spin Test
First, determine if the E5 code is related to the fan motor. Turn the AC off at the main breaker.
- Gently lift the horizontal flap on the indoor unit and use your fingers to push the cylindrical blower wheel.
- Spins freely: The bearings are good. The issue is electrical (Motor, Capacitor, PCB) or Gas related.
- Hard to spin / Jammed: The motor bearings have seized or the blower wheel has snapped. You need a mechanical replacement of the motor.
Step 2: Inspecting the Fan Wiring & Capacitor
If the blower spins freely but the AC throws E5 within 10 seconds of powering on, check the indoor PCB.
| Check Point | Expected Condition | Action if Failed |
|---|---|---|
| Motor Harness | Plugs securely fastened, no rat bites on wires. | Reconnect plugs. Solder/tape any chewed wires. |
| Fan Capacitor (Non-Inverter) | Small black box (e.g., 1.2µF to 2.5µF). Top should be flat. | If swollen or melted, unsolder and replace the capacitor. |
| DC Voltage (Inverter BLDC Motor) | PCB should send ~300V DC and 15V DC to the motor plug. | If voltage is 0V, replace PCB. If voltage is present but fan won’t spin, replace Fan Motor. |
Step 3: Evaluating for Low Refrigerant Gas
If your fan motor spins perfectly fine at high speed, but the E5 error appears after 10 to 15 minutes of operation, your Lloyd AC is flagging a Low Gas Protection mode.
When refrigerant is low, the indoor coil drops below freezing temperatures. The AC stops the compressor to prevent a massive ice block from forming and breaking the plastic chassis. A technician must attach a manifold gauge to the outdoor unit. If standing pressure is below 100 PSI (for R32), you have a leak that must be brazed and recharged.
Step 4: The Feedback (Hall IC) Test
If the fan motor spins, but only very slowly, and then triggers E5, the Hall IC (Feedback Sensor) inside the motor has likely died. The PCB commands a speed, but doesn’t get the RPM pulse back, so it shuts down. The motor must be replaced.
DIY Repair vs. Professional Service
Pros of Professional Repair
- ✓ Accurate Diagnosis: Pros easily distinguish whether E5 is a fan motor issue or a gas leak issue based on the timing of the error.
- ✓ Proper Motor Sourcing: DC Fan motors vary wildly in wattage, shaft length, and rotation direction. Pros get the exact OEM match for your Lloyd unit.
- ✓ Leak Detection: If the issue is low gas, professionals will pressure test with nitrogen to fix the leak rather than just blindly refilling it.
- ✓ Safe Handling: Inverter PCBs output 300V DC to the fan motor. Pros know how to test this safely without electrocution.
- ✓ Warranty Protection: Certified technicians provide warranties on the parts and gas they supply.
Cons of DIY (Do It Yourself)
- ✗ Misdiagnosing the Fault: Buying a new $100 fan motor only to realize your AC just had a $50 gas leak.
- ✗ Breaking Plastic Clips: Removing the indoor unit’s casing to get to the motor often results in snapping the brittle plastic chassis tabs.
- ✗ Blower Wheel Damage: The set screw holding the blower wheel to the motor rusts tightly. DIYers often snap the wheel trying to force it off.
- ✗ Shorting the PCB: Accidentally touching the 15V and 300V pins together while testing will instantly blow the main microprocessor.
- ✗ Illegal Gas Venting: Attempting to mess with refrigerant lines without recovery gear is dangerous and terrible for the environment.

Frequently Asked Questions
1. How do I know if E5 is the fan or low gas?
Timing. If E5 pops up within 10 to 30 seconds of turning on the AC and the blower never spins, it’s the fan motor. If the AC runs fine, blows cool air, but trips E5 after 15-30 minutes, it’s low gas.
2. Can I run my Lloyd AC with the E5 error?
No. The AC will lock you out to prevent damage. If the fan is dead, running the compressor will freeze the coil. If gas is low, running it will burn out the compressor.
3. Do rats cause the E5 error?
Yes, very often. Rats chew through the thin communication and feedback wires connecting the fan motor to the main PCB, causing an immediate E5 fault.
4. Can I fix an E5 error by resetting the AC?
If it was a temporary power surge confusing the motor’s Hall IC, a 5-minute breaker reset might clear it. If the motor is dead or gas is leaking, it will return.
5. Why is my blower wheel stiff to turn?
The bearings inside the motor have failed, or the rubber bushing on the left side of the chassis has seized. Lubrication rarely works; the motor or bush must be replaced.
6. Can a dirty AC cause E5?
Yes. If the blower wheel is heavily caked in dust and mold, it becomes very heavy. This strains the motor over time, leading to premature bearing failure and the E5 error.
7. Are Lloyd and Havells fan motors the same?
Usually, yes, since Havells manufactures Lloyd. However, you must match the exact wattage (e.g., 20W vs 30W) and shaft length. An incorrect motor will vibrate loudly.
8. Can I just replace the capacitor to fix it?
If you have a non-inverter AC, a $10 capacitor replacement often fixes E5. If you have a modern Inverter AC, the motor uses BLDC technology and does not have an external run capacitor.
9. Does Atlas Aircons repair Lloyd PCBs?
Yes, if your motor is fine but the PCB’s fan driver circuit is blown, we can perform component-level repairs on the mainboard to restore fan power.
10. How do I know if my AC is leaking gas?
Aside from the E5 code (after 15 minutes), look for ice forming on the thin copper pipe at the outdoor unit, or oily stains around the indoor/outdoor pipe connection nuts.
