HOW TO REPLACE THE TH SENSOR IN RCOM 20 INCUBATORS

This short blog post is a step-by-step guide explaining how to replace the temperature and humidity sensor in Rcom Max/Pro 20 incubators. The temperature and humidity sensor is the component that reads the temperature and humidity of the air circulating inside the incubator and is mounted inside the upper body of the incubator.

If the display shows ERR01 and/or unrealistic measured temperature and humidity values, this means that the sensor is faulty and needs to be replaced.

To replace the temperature and humidity sensor, follow the steps below:

Step 1. Disconnect the power

To be completely safe, turn off the power at the wall socket. Then, remove the plug from the wall.

Step 2. Remove the viewing window and egg tray

Carefully remove the viewing window and the egg tray which may be inside. It is recommended to place them on a towel or soft material to avoid scratches.

Step 3. Separate the top and bottom bodies of the incubator

Open the side locks of the incubator to separate the upper and lower bodies; place the upper body upside down on a work surface. It is recommended to place it on a towel or soft material to avoid scratching the display.

Step 4: Remove the screws from the black plastic cover

Unscrew the eight steel screws to remove the heating cover, marked in the figure above.

Step 5: Remove the screws from the control panel cover

Unscrew the four screws marked in the figure above to remove the cover from the control panel housing.

Step 6: Remove the temperature and humidity sensor

The temperature and humidity sensor is a small electronic component that is mounted on the printed circuit board.

Step 6.a. Remove the printed circuit board

Pull upwards until the printed circuit board (1) containing the sensor is completely detached.

Step 6.b. Replace the damaged temperature and humidity sensor

Attention: the sensor is a small and sensitive part, so you must be extremely careful not to break it.

With extreme care, use your fingers (thumb and forefinger) and grasp the sensor by its base (1), making small, gentle swings to the left and right, while slowly pulling the sensor upwards until it comes off all the pins. You can use a mini screwdriver (2) to help you with the process. See the images above.

Detaching the plug should be a controlled procedure. If you make quick, jerky movements, you risk breaking the sensor.

Step 7: Insert the new temperature and humidity sensor

Simply push the new sensor onto the pins on the circuit board carefully (1). Once again, the sensor should fit easily and not require too much force.

Next, insert the integrated circuit board back into the socket, pushing it all the way in (2), and then screw on the control panel housing cover and the black heating cover.
