By replacing the electro motor, which powers the blades in the fan, users kan keep using their fan heater for much longer. This electro motor (yj58-12a1) is very easy to acquire online, and fairly easy to replace.
We will provide a step-by-step manual to disassemble the fan heater down to the motor by unscrewing the housing and the parts inside the housing, taking the parts apart, cutting the wire, connecting the new wire and engine to the old wire and assembling the whole thing back together.
Minimal tools are needed to do so. We used Pozidrive screwdrivers (1x75), a small pick, pliers, stripping pliers, heat shrink sleeves, a lighter and some lubricant to disassemble the product and replace the motor.
