Temperature Sensor Errors: H14 and H17

When your Panasonic HZ Series air conditioner isn’t working right, it could be the temperature sensors. The H14 error code tells you there’s a problem with the indoor sensor. Meanwhile, the H17 error code means the outdoor sensor is acting up. Fixing these is key to keeping your air conditioner running well.

Identifying Temperature Sensor Faults

If your air conditioner shows weird temperatures, you might have a sensor problem. The H14 error code means the indoor sensor is reading temperatures wrongly, like way too hot or cold. The H17 error code says the outdoor sensor has issues too. Knowing these problems helps keep your air conditioner cooling efficiently.

Replacing Faulty Temperature Sensors

To fix these, you often need to replace the bad sensors. The Panasonic HZ Series manual tells how to do it right. It mentions using a R.T.D. input unit (AFP3421) that works with two types of sensors. These sensors cover a wide range of temperatures:

• -100°C to +200°C (-148°F to +392°F)
• -100°C to +50°C (-148°F to +122°F)
• -50°C to +100°C (-58°F to +212°F)
• -20°C to +80°C (-4°F to +176°F)
• +50°C to +200°C (+122°F to +392°F)

There’s a table that shows which sensor problems match which error codes:

Replacing bad sensors helps your air conditioner work right. It makes sure the temperatures are correct. This stops the air conditioner from breaking down and keeps you cool without trouble.

Compressor and Load Current Errors: H15 and H16

Panasonic HZ Series air conditioners are top-notch for efficiency and reliability. But, they can run into issues like H15 and H16 error codes. These codes signal compressor and load current problems. Such problems can affect the air conditioner’s working and lifespan.

Signs of Compressor and Load Current Issues

Spotting compressor errors and load current issues starts with knowing the signs. For the H15 error, the compressor temperature sensor might be faulty. This problem means there’s likely an issue with the wiring or sensor connector. The H16 error points to problems in the outdoor current transformer (CT). This could be due to outdoor PCB faults or issues with the compressor. Many cases need detailed checks for a proper fix.

Diagnosing Compressor Load Current Drop

Fixing compressor errors and load current problems needs several steps. First off, checking freon levels and looking for leaks is crucial. A loss in load current might come from transformer issues or power module faults. Different Panasonic HZ Series models may show different rates of H15 and H16 errors. Luckily, self-diagnosing can solve these problems effectively, addressing issues like solder joint failures or faulty parts.

Steps to Rectify Sensor and Current Issues

To fix H15 and H16 errors, follow these steps:

1. Inspect the compressor temperature sensor’s wiring and connectors for damage or disconnection.
2. Check the outdoor current transformer (CT) for issues, and replace the outdoor PCB or compressor if needed.
3. Make sure freon levels are right and there are no leaks.
4. Look at the power transistor module, replacing it might fix compressor issues.

These steps can help fix load current issues and boost your air conditioner’s effectiveness.

Grasping, diagnosing, and fixing H15 and H16 errors in Panasonic HZ Series air conditioners helps manage problems effectively. Regular checks and maintenance keep these advanced units running smoothly.
