Frequently Asked Questions
•What is the typical resistance range I should see from a functioning moisture sensor, both dry and wet?
When dry, a good moisture sensor should have a very high resistance, typically in the megaohm range (e.g., 1-10 megaohms or higher). When damp, the resistance should drop significantly, usually to the kilohm range (e.g., 10-100 kilohms). The exact values can vary depending on the specific sensor, but a significant change is the key.
•How do I access the control board to inspect or replace it?
To access the control board, you'll typically need to unplug the dryer and remove the top panel. This usually involves removing screws at the back of the dryer and then sliding the top panel either forward or backward. Once the top panel is removed, you should be able to see the control board. Be careful when disconnecting and reconnecting wires to the control board; take pictures for reference.
•Where is the dryer's grounding wire located, and how do I ensure it's properly connected?
The grounding wire is usually a green or bare copper wire connected to the dryer's metal chassis. It is often located near the back panel where the power cord enters the dryer. Ensure the wire is securely attached to the chassis with a screw or other fastener. A loose or corroded connection can affect the moisture sensor's performance.
