I'm reaching out regarding a recent issue we've encountered with one of our heating elements. The unit is heating up as expected, but we've noticed that the fan is not turning on at all. This seems to indicate a potential problem, and we are concerned it may be related to the circuit board. Could you provide your insights on this matter? Specifically, we'd appreciate your expertise on whether this is a common issue and what troubleshooting steps we should take. Additionally, any recommendations for replacements or repairs would be very helpful. Your assistance in resolving this matter quickly would be greatly appreciated. Thank you!
