Throughout the evaporator, there’s a small fan accountable for driving chilly air and evenly distributing it all through the fridge compartment. This fan contains a motor and rotating blades, very like every other fan.
Nonetheless, if ice and frost accumulate round these fan blades, they will generate the knocking noise you’re at the moment troubleshooting. This happens as a result of the spinning fan blades repeatedly come into contact with the ice buildup, ensuing within the noise.
A key indicator that that is the basis trigger is the fast and steady nature of the knocking sound, significantly when the fan is operational.
To resolve this challenge, you’ll be able to eradicate the ice and frost buildup across the evaporator fan blades. Nonetheless, if the buildup is substantial and difficult to take away, it might be essential to defrost the fridge and permit the ice and frost to soften away.
2 Water Pipes
