Fix Old Sanyo Aircon Blinking Lights & Leaks

If you own a Sanyo air conditioner in Singapore, you own a true “workhorse.” You have a piece of durable Japanese engineering that has likely provided you with years, or even decades, of reliable, no-frills cooling. During its time, Sanyo was a popular, budget-friendly choice for HDB and condo owners, and the fact that so many of these units are still running today is a testament to their original build quality.

However, as the owner of a legacy Sanyo system, you face a unique challenge. Since the brand was officially phased out around 2012 after its acquisition by Panasonic, your aircon is now at least 12 years old. Finding new parts and, more importantly, finding technicians with the specialized knowledge to service these older, non-inverter systems has become incredibly difficult.

At Vedha Aircon, we are Sanyo preservation specialists. We believe a reliable workhorse deserves a long life. We have the expertise, the diagnostic skills, and the resourceful network needed to maintain and repair the very legacy Sanyo systems that other companies might simply tell you to replace. Don’t give up on your trusted aircon; let our experts give it a new lease on life.

The Sanyo Legacy Specialist: Why Choose Vedha?

Servicing a 15- or 20-year-old Sanyo aircon is not a job for a generalist technician trained only on modern inverter units. It requires a deep, specific skillset and a problem-solving mindset.

• Expertise in Older Technology: The vast majority of Sanyo units in Singapore are non-inverter models that use R22 refrigerant. Our senior technicians are highly proficient in the diagnostics and repair of these older systems, a skill that is becoming increasingly rare.
• Unmatched Parts Sourcing Network: This is our greatest advantage and your best hope for a successful repair. We specialize in the difficult task of sourcing parts for discontinued Sanyo models. Whether it’s finding New Old Stock (NOS), reconditioned PCBs, or compatible fan motors and thermistors, we have the network and expertise to find the components needed to fix your unit.
• Honest “Repair vs. Replace” Advice: As the owner of an aging system, this is your most important question. We provide an honest, transparent assessment. For a major failure like a seized compressor on a 20-year-old unit, we’ll advise that a replacement is more economical. However, for common electronic faults or sensor issues, a professional repair is a highly cost-effective solution that can give you several more years of service.
• Careful Handling of Aging Components: We know that after more than a decade, the plastic casings and louvers on your Sanyo unit can become extremely brittle. Our technicians handle these delicate parts with the utmost care during servicing to prevent the cracks and breakages that are common with inexperienced handling.

Our Specialized Services for Your Legacy Sanyo Aircon

Our services are specifically tailored to address the common age-related issues of Sanyo air conditioners.

Sanyo Aircon Repair

We breathe new life into your old and reliable Sanyo.

• Blinking Light Diagnosis: This is the most common symptom of a fault. Our technicians are experts at decoding the specific error codes indicated by the blinking lights, allowing for a fast and accurate diagnosis of the underlying problem.
• PCB & Electronic Faults: A failed Printed Circuit Board (PCB) is a common issue in older units. We specialize in sourcing and installing replacement boards for common outdoor unit models like the SAP-CM3036S, restoring your system’s “brain.”
• Fan Motor & Thermistor Replacement: We can solve issues like screeching noises or poor temperature control by replacing worn-out fan motor bearings or faulty temperature sensors, some of the most common failures in aging units.

Sanyo Chemical Overhaul: A Rejuvenation Service

After more than a decade of service, your Sanyo’s internal components have accumulated a deep layer of stubborn dust, mould, and grime. A chemical overhaul is the only way to restore your workhorse’s performance. This process involves completely dismantling the indoor unit to deep-clean every part, restoring cooling efficiency, eliminating foul odors, and improving air quality.

Sanyo R22 Refrigerant Handling

Many older Sanyo units use R22 refrigerant, which requires certified handling. Our technicians are fully licensed and equipped to safely manage, repair, and recharge R22 systems in compliance with all environmental regulations.

We Service All Sanyo Systems Still in Operation

Our deep knowledge of the Sanyo brand’s history in Singapore means we are familiar with the specific models still running in homes and businesses today.

• Non-Inverter Multi-Split Systems: The core of Sanyo’s legacy. We are experts on the “Flexi-Multi” series and common outdoor models like the SAP-CM2426S and SAP-CM2036SA, which were the go-to solution for HDB flats and condos.
• Non-Inverter Single-Split Systems: We service the thousands of single-split units, with common models like the SAP-K256S, that were installed to cool master bedrooms and small offices.
• Ceiling Cassette & Ducted Systems: While less common, we also have the expertise to service Sanyo’s legacy commercial units found in older retail spaces and landed properties.
