E.The display reads “Sail Switch Closed Fault”. (Refer to page 52)

1.Prior to start up, the sail switch is in the closed position.

2.Check the sail switch and readjust accordingly.

3.Replace sail switch, if necessary.

F.The display reads “Burner Ignition Control Fault”. (Refer to page 52)

1.Check for 24 VAC at the Direct Spark Ignition (DSI) module across MV and GND. If no voltage, replace the DSI module. If voltage is present, check for 24 VAC at the gas valve on terminals 1 and 2. If no voltage, check for a loose connection on the wires going back to the DSI module. If voltage is present, proceed to Step #2.

2.Make sure the gas valve shutoff is in the on position.

3.Make sure proper gas pressure is supplied to the gas valve (6.0-12.0 inches [14.92-29.9 mb] water column [W.C.] for natural gas and 10.5 inches [26.1 mb] water column for liquid propane [L.P.] gas).

G.Tumbler will not rotate (non-reversing models), display reads “Rotation Fault”. (Refer to page 53)

1.Possible causes:

a. Belt is broke, loose, or slipping.

b. Lint accumulation on the rotational sensor.

c. Rotational sensor magnet is missing or broke. Reset power, then, restart the dryer.

d. Check for 24 VAC at the computer board J8 connector pin 7 blue/silver wire to GND. If no voltage is present, check for a loose connection, if connection is good, replace computer. If voltage is present, proceed to next step.

e.Check for 24 VAC on the motor contactor A1 to A2. If no voltage, check for a loose connection in the wire. If voltage is present, proceed to next step.

f.Check for 24 VAC on the motor contactor across T1 and T2. If no voltage, replace motor contactor. If voltage is present, proceed to next step.

g.Use a nonconductive device (i.e., wooden pencil) to push in on the motor contactor. If motor does not come on, the problem is a faulty motor.

With a maximum drying capacity of 30 pounds, the AD-30 features a robust construction that can withstand the demands of heavy usage. Its powerful airflow technology ensures quick drying times, improving productivity and minimizing energy consumption. The dryer is equipped with a microprocessor control that offers multiple cycle options and customizable settings, allowing operators to tailor each drying cycle based on the specific fabric types being processed.

On the other hand, the AD-25 serves smaller operations with a capacity of 25 pounds, making it an efficient choice for businesses with moderate laundry needs. Similar to the AD-30, it incorporates advanced airflow technology to enhance drying efficiency. The AD-25 also features easy-to-use controls and programmable settings, providing flexibility for various drying requirements. Both models come with an easy-to-clean lint filter that helps maintain optimal air quality and prolongs the life of the machine.

In terms of construction, both dryers are built with durability in mind. Their stainless steel exteriors are not only aesthetically pleasing but also resistant to corrosion, ensuring they remain in good condition over time. The design of these dryers incorporates vibration reduction systems to minimize noise during operation, contributing to a more pleasant working environment.

Energy efficiency is a hallmark of American Dryer Corp products, and both the AD-30 and AD-25 are no exception. They are designed to consume minimal energy while delivering maximum drying performance, which can lead to significant cost savings over time. Additionally, the dryers are engineered with safety features, including over-temperature protection and a non-reversible door to prevent accidents.

In summary, American Dryer Corp's AD-30 and AD-25 dryers exemplify the brands' commitment to providing quality, efficiency, and reliability in commercial laundry operations. With their advanced technologies and user-friendly features, these dryers are well-equipped to meet the diverse needs of the laundry industry.
