Welcome to Watson's Appliance Parts & Service. We are a family-owned business located in Stillwater. We can service all of your household products as well as supply parts for do-it-yourselfers. No matter the brand we can service your appliances. Call us today and let us help you get back to your normal life without any hassle.

"The scheduler I first talked to was very pleasant and thorough regarding my needs. A few days later Tim N. and another technician came at my request because I thought the refrigerator had to be pulled out of its very tight space. Tim immediately recognized there was no need for a second technician. I was not charged for that second technician. Tim pulled the bottom freezer door out, found that the fan in the freezer assembly had a bent blade, fixed that and he was done within an hour. Now the refrigerator runs almost silently. Quick and efficient service at a reasonable price. I would definitely use Watson Appliance for service again and would recommend them to a friend."

FAQs for water heater repair or service projects in Cottage Grove, MN

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
