Frequently Asked Questions
•What is the typical resistance range I should expect from the moisture sensor when dry vs. wet?
Typically, you'll see a very high resistance (near infinite) when the sensor is dry and a lower resistance (e.g., 10k to 100k ohms) when wet, depending on the amount of moisture. Consult the service manual for specific values.
•Where can I find the wiring diagram for this specific Speed Queen dryer model?
Wiring diagrams are usually located inside the dryer cabinet, often attached to the back panel or control panel. You can also obtain them from a Speed Queen parts supplier or the manufacturer's website.
•If the control board voltage is within range, but the sensor still doesn't detect dryness, what else could be the issue?
Double-check the grounding. A weak or intermittent ground to the dryer chassis can falsely trigger the 'wet' reading. Also, ensure the sensor bars are making good contact with the clothes, as heavy fabric conditioners can leave a residue.
