Setup and Installation
Proper installation of the charcoal filter is crucial for effective odor reduction. Please follow these steps carefully. Always ensure the microwave is unplugged before beginning any installation or maintenance.
- Safety First: Unplug the microwave oven from its power outlet to prevent electrical shock.
- Locate the Vent Grill: The charcoal filter is located behind the vent grill, typically found at the top front of the microwave oven.
- Remove the Vent Grill:
- Depending on your specific Whirlpool model, the vent grill may be secured by screws or latches.
- If screws are present, use a screwdriver to remove them. Keep them in a safe place.
- If latches are present, gently push or pull them to release the grill.
- Carefully pull the vent grill away from the microwave.
- Remove the Old Filter: Once the vent grill is removed, you will see the old charcoal filter. Note its orientation. Gently pull or slide the old filter out of its slot.
- Install the New Filter:
- Unpack the new Lazellz charcoal filter.
- Insert the new filter into the filter slot, ensuring it is oriented correctly, matching the way the old filter was installed. The metal mesh side typically faces outwards.
- Push the filter firmly until it is securely in place.
- Reattach the Vent Grill: Align the vent grill with its opening and secure it back into place. If there were screws, reinsert and tighten them. If there were latches, ensure they click into position.
- Restore Power: Plug the microwave oven back into its power outlet.
Your microwave is now ready for use with the new charcoal filter.
Operating Principles
The charcoal filter functions passively during microwave operation. When the microwave's exhaust fan is activated, air from the cooking cavity is drawn through the charcoal filter. The activated charcoal within the filter absorbs cooking odors, helping to keep your kitchen air fresh. No specific user action is required for the filter to operate once installed.
Maintenance
Regular maintenance of your charcoal filter ensures optimal performance in odor reduction.
- Replacement Frequency: It is recommended to replace the charcoal filter approximately every 9 months. However, replacement frequency may vary depending on the intensity and frequency of microwave use.
- Signs for Replacement: Replace the filter sooner if you notice that the air from the exhaust fan no longer smells fresh, or if cooking odors persist in your kitchen after microwave use.
- Cleaning: Charcoal filters are not designed to be cleaned or washed. Attempting to clean the filter will reduce its effectiveness. Always replace with a new filter.
Troubleshooting
If you encounter issues after installing your new charcoal filter, consider the following:
- Persistent Odors: If odors remain after replacing the filter:
- Ensure the filter is correctly seated in its slot and the vent grill is properly reattached.
- Verify that the microwave's exhaust fan is functioning correctly.
- Confirm that you have the correct filter type for your microwave model.
- Filter Does Not Fit: If the new filter does not fit into the designated slot:
- Double-check your microwave's model number against the compatible models listed in this manual (MH1170XSS1, MH1170XSS2, MH1170XSS3, MH1170XSS4).
- Ensure the filter is not being inserted incorrectly (e.g., upside down or backward).
