Customer States: They have no hot water. They have been without hot water since Thursday of last week. Technician Notes: There is a 40 gallon natural gas Whirlpool waste heater from 2008 in the exterior utility closet that is not producing hot water. Pilot will not stay lit. Due to the pilot going out, burner assembly is unable to turn on. Thermocouple has failed. Resolution: Submit work order to CHW for approval. CHW approved replacement of the thermocouple. After installing the new thermocouple, the water heater pilot would still not work properly. Issue is more then likely related to the gas control valve. I am unable to locate the exact one of this water heater. This unit is 16 years old and whirlpool was the manufacturer. Unable to locate part. Water heater will need replaced. Job Notes: No exterior sewer clean out located while onsite today. Job Status: Complete ( customer may need new work order for water heater replacement ) Autho: auth37055030 for 130.00 Estimates: Goo
