What aircon float switch repair covers

A water-level code normally means the protection saw water or lost the level signal. It does not prove the switch itself caused the overflow.

  • A float-switch, drain-level or water-level code appears

  • A cassette or ducted unit stops with water in the pan

  • Overflow protection returns after the drain was cleared

When to start elsewhere

These conditions can create the same symptom or protection code and need a different starting point.

What we check before float switch repair

The water path is tested before the switch. We inspect the pan and pipe, confirm pump operation, then check float movement and the electrical signal.

  • Indoor model and drainage arrangement

    This establishes the correct diagnostic path before any component is tested.

  • Drain pan, trap, pipe route and outlet flow

    We compare the source condition with what reaches the affected circuit under load.

  • Pump operation and supply where fitted

    We inspect this part of the connected path for the same stop, trip or abnormal reading.

  • Float movement, connector, harness and PCB input

    This separates the named component from its wiring, controls and connected load.

What you get

Float shapes, mounting positions, connectors and pump arrangements vary by indoor unit. We confirm the exact drainage assembly before ordering.

  • A model-specific diagnosis instead of a parts guess

  • A clear explanation of what failed and what tested normally

  • A repair scope and quote before compatible parts are ordered

Brand-specific float switch repair

Choose the brand for its model scope, official diagnostic evidence, parts path and repair-versus-replacement guidance.

Workmanship warranty

We stand behind the repair we carry out, and we are straight about the part of the cover we do not set ourselves.

Labour

30-day labour warranty. If the same fault returns from the repair we did, we come back and the labour is on us, with no second diagnosis fee.

Parts

Parts follow whatever warranty the distributor sets for that component, so the term varies by part. We tell you the coverage before you approve the quote.

Frequently asked questions about aircon float switch repair in Singapore

Does an error code prove the float switch has failed?
A water-level code normally means the protection saw water or lost the level signal. It does not prove the switch itself caused the overflow.
How do you confirm an aircon float switch fault?
The water path is tested before the switch. We inspect the pan and pipe, confirm pump operation, then check float movement and the electrical signal.
Can the float switch be replaced on its own?
Float shapes, mounting positions, connectors and pump arrangements vary by indoor unit. We confirm the exact drainage assembly before ordering.
Should I repair or replace the aircon?
A contained wiring, sensor, switch, valve-coil or driver-stage repair can make sense when the rest of the system is healthy and the correct part is available. On an older system with multiple major faults, compare the complete repair with replacement before committing.
