Haier Air Conditioner Capacitor Parts

OEM Haier Air Conditioner Capacitor Parts

A failing capacitor in your Haier AC is one of the most common—and easiest—failures to fix yourself. When the run capacitor weakens, your compressor and fan motor lose their electrical kickstart, leaving you with a humming unit that won't cool. Haier units are popular compact and window systems, and their capacitors follow strict microfarad specifications. Installing the wrong rating will toast your motor in days.

We carry original Haier capacitors in every voltage and microfarad rating. Get your exact replacement by looking up your model number, or browse our full Haier air conditioner capacitor parts inventory today.

• Humming compressor: Run capacitor no longer holds electrical charge
• Unit won't start: Start capacitor failure prevents initial motor rotation
• Short runtime: Weakened capacitor causes compressor to overheat and shut off
• Bulging or leaking: Capacitor casing ruptures, spilling dielectric oil
• Voltage damage: Installing 370V capacitor in 440V circuit or vice versa

Haier Air Conditioner Capacitor Replacement FAQs

Is it safe to replace a Haier AC capacitor myself?

Yes, if you follow proper safety steps. Capacitors hold electrical charge even when power is off, so *always* discharge the capacitor using an insulated screwdriver before touching it—short the leads together to ground any residual voltage. Wear work gloves and safety glasses. If you're uncomfortable handling electrical parts, call a technician. Most Haier window and compact units have accessible capacitors mounted near the compressor, making DIY replacement straightforward for confident homeowners.

What microfarad rating do I need for my Haier capacitor?

Your Haier model's exact capacitor microfarad (µF) and voltage rating are printed on the original part itself, or on the wiring diagram inside your unit's panel. Common Haier specs are 15µF/370V, 25µF/370V, or 20µF/440V depending on the model size. Buying a capacitor with the wrong microfarad rating will cause the compressor to draw excess current and fail. Always photograph your old capacitor before removal so you have the specs in front of you while shopping.

How long do Haier AC capacitors typically last?

Most capacitors last 3–5 years in regular use, but Haier units running 8+ hours daily in hot climates can see capacitor failure in 2–3 years due to heat stress. If your Haier is older than five years and the compressor is humming without cooling, capacitor replacement is very likely. Preventive replacement of aging capacitors saves you from sudden summer breakdowns and protects your compressor from strain.

Why is my Haier AC compressor humming but not cooling?

A humming compressor almost always means a weak or dead run capacitor. The motor has enough juice to hum but not enough to actually turn the compressor shaft, leaving your Haier blowing warm air. This is one of the easiest fixes—a new OEM Haier capacitor restores cooling in minutes. Don't ignore the humming; continued strain on the compressor without the capacitor's support can damage the motor windings permanently.

Find the Model Number on Your Haier Air Conditioner

On Haier air conditioners, look for the model number on a label on the side of the cabinet. Window and portable units may also have the label behind the front grille or inside the filter panel, so check those spots if the side label is missing. The model number identifies the whole unit, not just a capacitor or another individual part. Enter it in the model number search to pull up the parts matched to your unit, then use the filtered results across the catalog for any repair. This quick check helps you avoid comparing incompatible specifications and puts the correct Haier parts within reach.
