IPM Module in Air Conditioner: Understanding Functions and Signs of Failure

Modern inverter air conditioners use complex electronic components to ensure efficient and smooth operation. One of the key elements is the IPM (Intelligent Power Module). It plays a vital role in controlling the compressor and fans, providing precise power regulation and energy efficiency. In this article, we will take a detailed look at what an IPM module is in an air conditioner, what functions it performs, and what signs indicate its possible failure, relevant for air conditioner owners in Kyiv and throughout Ukraine.

What is an IPM Module in an Air Conditioner?

An IPM module is a hybrid power device that integrates power transistors (usually IGBTs), control circuits for these transistors, as well as protection circuits against overloads, short circuits, and overheating. The main function of the IPM module is to convert direct current into alternating current of the required frequency and amplitude to power the compressor and fan motors of the inverter air conditioner. This allows for smooth regulation of their rotational speed, which ensures precise maintenance of the set temperature, reduces noise levels, and decreases energy consumption.

Main Functions of the IPM Module in an Air Conditioner:

• Compressor control: Ensures smooth start-up and regulation of the compressor's rotational speed, which is key to inverter technology.
• Fan control: Controls the rotational speed of the indoor and outdoor unit fans, optimizing airflow and heat exchange efficiency.
• System protection: Built-in protection circuits safeguard the compressor and other components from overloads, short circuits, overheating, and other emergency situations.
• Increased energy efficiency: Precise power control allows the air conditioner to consume exactly as much electricity as needed to maintain the set temperature.

When the IPM Module Fails: Main Signs of Malfunction:

Failure of the IPM module can lead to serious problems in the operation of the air conditioner. Here are the main signs that may indicate its malfunction:

• The air conditioner does not turn on: If the IPM module has completely failed, it may block the power supply to the compressor and fans, and the air conditioner will not turn on.
• Lack of cooling or heating: If the IPM module cannot correctly control the compressor, the air conditioner will not produce cold or hot air.
• Uneven compressor operation: The compressor may operate jerkily, with unusual noises or vibrations due to incorrect control by the IPM module.
• Fan problems: The indoor or outdoor unit fans may not rotate, rotate at less than full speed, or operate erratically.
• Protection tripping and air conditioner shutdown: The built-in protection circuits of the IPM module may trip when internal problems are detected, leading to spontaneous shutdown of the air conditioner.
• Appearance of error codes related to the power section: Specific error codes may appear on the air conditioner's display indicating problems with the IPM module or the inverter's power section.
• Burnt electronics smell: In case of serious damage to the IPM module, a characteristic smell of burnt plastic or electronics may appear.

What to Do If You Suspect an IPM Module Failure?

1. Disconnect the air conditioner from the power supply to prevent further damage.
2. Contact a qualified technician for professional diagnostics. Diagnosing an IPM module requires specialized knowledge and equipment.
3. If the IPM module failure is confirmed, purchase a high-quality original or certified aftermarket module in our online store Only-Spares in Kyiv with delivery throughout Ukraine. We offer a wide selection of IPM modules for various inverter air conditioner models.
4. Entrust the replacement of the IPM module to an experienced specialist, as this procedure requires precision and knowledge of electrical engineering.
