Roper Dryer Lint Filter Housing Clogged: How to Access... | appliancefaults.com

Technical Background:

The dryer's MCU (Main Control Unit) monitors exhaust temperature using a thermistor. Excessive lint buildup restricts airflow, causing the thermistor to report high temperatures. The MCU may extend the drying cycle or, in extreme cases, shut down the heating element as a safety precaution. Voltage paths related to the motor and heating element are crucial, and blockages affect these components' performance.

Symptoms:

The homeowner reports that the Roper dryer is taking longer than usual to dry clothes. They also notice a musty smell and suspect a lint buildup deep inside the lint filter housing that they cannot reach with their hand.

Possible Causes:

Infrequent lint filter cleaning.
Using dryer sheets improperly (can create a coating).
Restricted vent hose.
Poor dryer venting system design.

Solution:

1

Unplug the dryer from the outlet. Verify 0V AC at the outlet with a multimeter.
2

Remove the lint filter.
3

Use a 1/4-inch nut driver to remove the screws securing the lint filter housing. Usually 2-4 screws.
4

Carefully detach the housing. It might be held in place by clips, so gently pry it loose.
5

Use a vacuum cleaner with a hose attachment to remove any loose lint.
6

If the clog is stubborn, try using a dryer vent cleaning brush or a long, flexible brush to break it up. A shop vacuum can also be helpful.
7

Reassemble the lint filter housing and secure it with the screws.

Safety Warning:

Disconnect power before servicing. Lock Out/Tag Out (LOTO) the breaker panel to prevent accidental energizing of the circuit. High voltage (120V AC and 240V AC) is present inside the dryer.

Prevention:

Clean the lint filter after every load. Inspect and clean the dryer vent hose at least once a year. Consider using dryer balls instead of dryer sheets.

Expert Tip:

Some Roper dryers have a diagnostic mode. Consult the service manual for the specific model, but a common sequence involves pressing and holding two buttons simultaneously (often the 'Start' and 'End of Cycle' buttons) for a few seconds to access error codes.

Frequently Asked Questions

•How do I check for a blockage in the dryer vent hose?

Disconnect the vent hose from the dryer and the wall. Visually inspect the hose for any obstructions. Use a dryer vent cleaning brush to remove any lint buildup. Ensure the hose is not kinked or crushed.

•What type of dryer vent hose should I use?

Use a rigid or semi-rigid metal duct. Avoid using plastic or foil vent hoses, as they are a fire hazard and can easily trap lint.

•How often should I clean my dryer vent system?

At least once a year, or more frequently if you notice your dryer is taking longer to dry clothes.
