Step 1: Open the Remote Fan Casing

The first step is to gently pry open the casing of the remote fan using a small flathead screwdriver or a pry tool. Start at a corner and carefully work around the edges to separate the front and back casing.

The back side of the remote fan

Inspect the battery terminals and components for signs of corrosion. Corrosion often appears as a greenish or white buildup on the metal contacts.

Remove the battery cover and battery. 

Pry the casing.

Separate the casing using a flat screwdriver. 

Step 2: Access Internal Components

After opening the casing, lay the internal components on a clean surface. If screws hold the PCB, remove them using a Phillips screwdriver. Lift the PCB and other features that are secured inside the casing.

Remove PCB.

Remove keypad.

Step 3: Clean the PCB and Components

Gently disconnect any wire connections (if applicable) from the PCB. Use isopropyl alcohol and cotton swabs to clean the PCB and components, removing corrosion, dirt, or debris. Pay close attention to the battery terminal areas and wipe down plastic parts.

Clean keypad, PCB, and casing.

Step 4: Repair the Corroded Areas Using Corrosion Solution

If corrosion has affected the coil or plate in the battery compartment, apply a small amount of corrosion solution to a cotton swab. Apply the solution to corroded areas and gently scrub to remove corrosion. 

Spray the corrosion solution on the corroded areas.

Most of the corrosion is on the spring and flat plate of the battery terminal.

Use fine-grit sandpaper for stubborn residues.

Step 6: Assemble the Keypad, PCB, and Close the Casing

Align the keypad and PCB, making sure buttons match up with corresponding areas. Gently place them back into the casing. If screws held the PCB, reinsert and tighten them.

Align the keypad and PCB.

Tighten the screw using Philip's screwdriver.

Insert the battery and test before closing the casing.

Align and press the casing edges to ensure a secure fit.

Step 7: Test

Turn on the remote fan and test its functionality. Observe performance for any irregularities.

Test all functions of the remote fan.
