The fan on the Kelvinator Single Door Hardening Cabinet Flash Freezer keeps breaking. There seems that there is nothing to keep the fan on the motor and we get it fixed and a few months later it happens again. It makes a lot of racket for a few days before it dies. The time period between incidents is getting shorter. Is there anything that can be done?
If the fan motor shaft is smooth with 1 flat spot the hub on the blade probably has a hex set screw that can be tightned with an allen wrench. If the fan motor shaft is threaded there should be a nut holding the blade on. Also yur motor bearings could be going bad causing vibration which damages the fan blade.
Testimonial: "the bearings going out would explain why the problem happens with increasing frequency. Thanks."
