Introduction

ResMed AirSense 11 is a popular CPAP machine that is used to treat sleep apnea. It is designed to provide a comfortable and effective therapy experience for patients. However, like any other machine, it can encounter errors that can affect its performance. One of the most common errors that users encounter is the heating system error. This error can be caused by a variety of factors, including a malfunctioning heating element, a faulty temperature sensor, or a clogged air filter. In this article, we will provide you with instructions on how to fix the heating system error in your ResMed AirSense 11 machine.

Step-by-Step Instructions

Step 1: Check the Air Filter

The first thing you should do when you encounter a heating system error in your ResMed AirSense 11 machine is to check the air filter. A clogged air filter can cause the machine to overheat, which can trigger the heating system error. To check the air filter, follow these steps:

1. Turn off the machine and unplug it from the power source.
2. Locate the air filter cover on the back of the machine.
3. Remove the cover and take out the air filter.
4. Inspect the air filter for any signs of dirt or debris.
5. If the air filter is dirty, clean it with a soft brush or replace it with a new one.
6. Reinsert the air filter and replace the cover.
7. Plug in the machine and turn it on to see if the heating system error has been resolved.

Step 2: Check the Heating Element

If the air filter is clean and the heating system error persists, the next thing you should check is the heating element. The heating element is responsible for heating the air that is delivered to the patient. A malfunctioning heating element can cause the machine to overheat, which can trigger the heating system error. To check the heating element, follow these steps:

1. Turn off the machine and unplug it from the power source.
2. Remove the water chamber from the machine.
3. Inspect the heating element for any signs of damage or wear.
4. If the heating element is damaged, replace it with a new one.
5. Reinsert the water chamber and plug in the machine.
6. Turn on the machine to see if the heating system error has been resolved.

Step 3: Check the Temperature Sensor

If the heating element is functioning properly and the heating system error persists, the next thing you should check is the temperature sensor. The temperature sensor is responsible for monitoring the temperature of the air that is delivered to the patient. A faulty temperature sensor can cause the machine to overheat, which can trigger the heating system error. To check the temperature sensor, follow these steps:

1. Turn off the machine and unplug it from the power source.
2. Remove the water chamber from the machine.
3. Locate the temperature sensor on the bottom of the water chamber.
4. Inspect the temperature sensor for any signs of damage or wear.
5. If the temperature sensor is damaged, replace it with a new one.
6. Reinsert the water chamber and plug in the machine.
7. Turn on the machine to see if the heating system error has been resolved.
