Hi Gary, thank you for your inquiry. Based on our research, the error F-4 indicates the humidity sensor error. Yes, the humidity sensor, part number PS3529192, that you mentioned is possibly causing this error. You may need to replace it to fix the issue. Glad to be of assistance!

For model number LMHM2017SW
Hi Thomas, thank you for reaching out. According to our research, we would recommend checking the Thermostat, part number PS3530469. The thermostat senses the heat and turns the fan on. If you require assistance placing an order, please contact customer service. We hope that helps!
