Wisconsin has no separate appliance repair license; plumbing licensing covers appliances connected to water supply systems, including water heaters, but exempts minor repairs to appliances and repair or replacement of gas or electrical control valves and devices.

In Wisconsin, you can check a license with the Wisconsin DSPS LicensE credential lookup or report a problem to the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), Bureau of Consumer Protection.
Questions to Ask a Cottage Grove Technician
