Shark UltraCyclone CH951 U4 Power Control Board Replacement

Difficulty

Moderate

Steps

Time Required

20 - 35 minutes

Introduction

This guide will provide instruction for how to replace the power control board. The battery life of the Shark UltraCyclone CH951 is 15 minutes per 6 hours of charging. If you notice that the vacuum does not turn on at all, or is not staying on while fully charged, you may need to replace the power switch.

Please note that you must remove the battery connection first, as dealing with electric components could be potentially hazardous. However, the entire battery does not need to be removed.

Tools

Step 1

Press the dust cup release button and gently pull the dust cup away from the body of the vacuum.

Step 2

Use a TR9 Torx screwdriver to remove the two 8.7 mm screws previously behind the dust cup.

Step 3

Remove the two 12.2 mm screws underneath the dust cup button using a TR9 Torx screwdriver.

Step 4

Remove the 13.9 mm screw beneath the charging port using a TR9 Torx screwdriver.

Step 5

Use the TR9 Torx screwdriver to remove two 11.6 mm screws that hold the exterior motor in place.
They are located underneath where the dust cup previously was and above the exterior motor.

Step 6

Run an iFixit Opening Tool under the casing along the vacuum body until the shell is removed starting around the attachment port, and sliding down towards the charging port.
If necessary, apply gentle force.

Step 7

Press down on the connection point of the white wire and disconnect it.
The connector looks like a white latch. Push down on the edge to pop it out of place.
