Safety First

Safety comes first when working on any appliance. Here are some practical tips to help keep you safe:

• Always turn off the power by unplugging the appliance or switching off the circuit breaker before starting. This protects you from the risk of electric shock.
• Wear insulated gloves to protect your hands from sharp edges, pinching hazards, or debris.
• Take your time and work at a steady pace to avoid accidents or injuries.
• Make sure your workspace is well-lit so you can clearly see and access the parts you’re working on.
• Keep your area organized and free of clutter, and ensure children and pets are kept away from the workspace.
• Never handle internal parts with wet hands. Make sure both your hands and the work area are completely dry.
• Check your appliance’s user manual for specific instructions or safety guidelines related to your repair.
• Handle parts gently to prevent damaging the appliance or injuring yourself by using too much force.
• Wear safety glasses if you’re dealing with chemicals, dust, or large debris to protect your eyes.
• If the appliance was recently used, give it time to cool down before working on any heated components.
• Take photos or notes of wiring connections before disconnecting anything. This makes reassembly much easier.
• Avoid touching exposed wires or terminals. If you need to handle wires, use non-conductive tools or wear insulated gloves to reduce the risk of electrical shock.

Removal and Disassembly Steps

1. Using a flathead screwdriver, gently compress the locking tab on the lens cover to release it from the grille assembly. Set it aside.
2. While securing the grille and reflector assembly with one hand, unscrew the light bulb with the other hand. Set aside the light bulb.
3. Using a 3/8-inch nut driver, loosen and fully unscrew the acorn nut located on the underside of the reflector assembly.
4. Carefully unplug the wiring connector attaching the reflector assembly to the light receptacle you’ll be replacing.
5. Remove the reflector assembly from the fan housing and set it aside safely.
6. Disconnect the plug attaching the exhaust fan wires to the exhaust fan receptacle.
7. Using a 1/4-inch nut driver, remove the hex head screw located on the side of the exhaust fan housing.
8. Gently pull down on the exhaust fan housing to detach it from the main bath fan assembly. Let it hang safely out of the way while leaving its wire connector plugged in.
9. Using a 1/4-inch wrench, loosen and fully remove the hex head screw located on the side of the receptacle bracket.
10. Pull down on the receptacle bracket to detach it, providing access to the back of the faulty light receptacle.
11. Loosen and fully remove the wire nut connections. 
12. With the wire nuts removed, fully separate and unwind each of the wire groupings to detach them from the faulty receptacle.
13. If you look closely at the perimeter of the receptacle housing, you’ll notice small locking tabs holding it in place. Using needle nose pliers, squeeze both tabs to release them.
14. With the tabs released, push forward on the receptacle to fully remove it from its bracket housing.
15. Set aside the faulty receptacle, as you won’t need it after installing its replacement.

Installation and Reassembly Steps

1. Carefully remove the new light receptacle from its packaging, avoiding touching/damaging the wire contacts themselves.
2. Orient and insert the new receptacle correctly into the now-vacant bracket housing, gently pressing it backwards until both perimeter locking tabs click securely into place.
3. Visually inspect the receptacle to make sure both tabs have fully engaged to hold it firmly in place within the bracket.
4. Take the two white (neutral) wire ends, one coming from the new receptacle and one from the bath fan housing, twist them together and screw on a wire nut. Gently pull on both wires to make sure you have a tight connection.
5. Repeat this process for the black (hot) wires.
6. Next, take the blue and red wires, twist them together with pliers, and cover the grouping with a wire nut, again checking for a tight connection.
7. Carefully return the collected wires and connectors back into the bath fan housing to keep them neatly managed.
8. Slide the receptacle bracket you removed in Step 4 back up into place between the heater housing and exhaust fan shroud.
9. Re-insert and tighten the bracket’s hex head screw using the 1/4-inch wrench.
10. Align the exhaust fan housing’s hanging metal tabs with the corresponding slots on the bath fan housing.
11. Feed its hex head screw into place and finger tighten while supporting the exhaust fan housing. Then fully tighten using the 1/4-inch nut driver.
12. Plug the exhaust fan wires back into their corresponding receptacle.
13. Feed the wiring for the reflector assembly through the center opening of the metal grille assembly.
14. Align the reflector assembly, insert and firmly screw the acorn nut into place with the 3⁄8 inch nut driver.
15. Plug the reflector assembly’s connector back into the new light receptacle you installed.
16. Carefully screw the light bulb back into the reflector assembly’s socket.
17. Hook one of the lens cover’s perimeter tabs into its corresponding slot on the metal grille assembly.
18. Bend the lens slightly and press firmly on its opposite side to fully snap the other tab securely into place.
19. Restore power to the bath fan via your home’s circuit breaker.
20. Turn on the fan and test its operation, ensuring normal airflow and that the light now functions properly without issues.
