Re: sail switch open fault
The sail switch is a safety device that turns of the dryer if insufficient airflow is detected out of the dryer vent. make sure the dryer vent is clear and air flow out of dryer vent is not obstructed in anyway.

Hello, in order for the humidifier to turn on and off with the furnace you need either a sail switch or current sensing relay. A sail switch mounts in the return air duct and senses the return air when the furnace turns on thus turning on the humidifier and turning it off when the airflow stops. A current sensing relay works the same way but instaed of sensing airflow in senses current on the blower motors common lead and is easier to install than a sail switch. I will post a pic of both
Review figures 5, 6 and 7 on the installation instructions and compare with how you wired your installation.
The red wires are not used if you use a mechanical humidistat, (are used with electronic humidstat - supplies 24 volts and go to "hot", "commod" on humidstat). Yellow wired to "Hum" whether electronic or mechanical humidistat used.
If using sail switch or current sensing relay, cuts into one of the yellow wires. - One yellow goes directly to humidisat, then comes out of other side of humidistat & runs to to relay (or sail switch), and comes out of relay (or sail switch) and runs back to humidifier.
Most the time I run across the F64 code it is due to the "sail switch" not being activated. I usually remove the bottom grill and lubricate the micro (sail) switch and actuator (the sail) with a zoom oiler (available at most hardware stores). A small drop is all that's needed. Then move the metal rectangular plate (the sail) back and forth to work in the oil. RARELY do I have to adjust the sail (that metal plate) to "catch" the air and activate the micro switch but that too may be necessary.
A sail switch is a Blower "on" proof switch. It's purpose is to prevent equipment such as air cleaners and/or humidifiers from energizing unless the blower is running. The sail switch literally has a sail that is put in the ductwork. When the blower starts, the airflow will push the sail so as to close a switch allowing accessory equipment to operate.
I hope you find this information to be very helpful to your moving forward. Let me know if you have any further questions, comments, or concerns.
Double check the circuit breaker for the dryer (Electric Neptune). Turn it off, then turn it back on. Its possible that the breaker may have tripped for some reason, but wasn't able to trip all the way.
Does the interior of the dryer get warm at all? You could have a 1 of multiple heating elements that has shorted. If no heat at all, the likely a heating element has opened up. Unplug dryer from wall (turn off circuit breaker first!). Use a ohm meter to measure and check continuity of the heating elements.
There may also be a sail switch in the air path of the dryer. The purpose of the sail switch is to keep the elements turned off until there is enough air blowing through the dryer. This helps prevent fires, as well as shrunken denim.
Thanks Marty for the info on the sail switch. We experience the same error code 43 problem. Seemed like the sail switch was stuck in the back position and didn't come forward when the fan started. So I bent a metal coat hanger and used it to pull the switch foward to "unstick" it. I tested the oven turning it on and off a few times and made sure that the switch moves forward with the blower fan starting when the oven was on, and moved back when the oven was turned off. Should be obvious, but make sure the blower is not running and the oven is turned off before you stick the wire hanger back there. A pretty quick and easy thing to try before calling the repairman.
Lower oven cooling fan air switch not detected
Replace air switch,replace cooling fan,check connections, check P6 on PCB
control display. f64 fault code is an issue with the lower oven cooling fan motor and, or (air) sail switch
