Powder Clinic: Batch Cure Oven Noise Issue
What is that Noise from My Oven? Expert Rodger Talbert explains that it is difficult to be sure at all without seeing the oven and hearing the noise. However, he thinks it may be related to the pressure settings on the gas train.

Q. We have a batch cure oven we recently purchased for our powder coating operation. It is making a loud humming noise every time it cycles down from the cure set point to a cooler temperature. The humming stops when the temperature is changed again. Any idea what the cause of the humming could be?
A. It is difficult to be sure at all without seeing the oven and hearing the noise. However, I think it may be related to the pressure settings on the gas train. The low fire setting may be too low, causing the pipe to throb at a certain temperature range. Have someone from the oven manufacturer explain to you how to raise the setting until the humming sound stops. If this does not work return the setting to the original positon and arrange a service visit from the manufacturer. They will be best equipped to help solve the noise issue.
