My mom had a bathroom remodel two years ago and we blieve the contractor installed the Glacier Bay 67604W-6004. We'renot 100 percent sure of the model number, because he passed away just prior to completing the entire remodel. The LED on the faucet stopped working few months ago and I checked the screens for her and they were clean. Is there anything else I should check. She's older and really relies on the faucet light at night. Thank you in advance, Marion User's recommendation: My mother loves the LED, but $20 is a lot to replace it when it stops working. It appears you have to replace part of the faucet not just the little LED insert protion.
