Dryer repair in Minneapolis, from the drum to the vent hood
In January, a dryer on the southwest side often fails at the far end of its vent rather than inside the cabinet. Outside, the vent hood is mounted low on the foundation, and a few nights of drifting snow can pack it shut or glaze the flap with ice. In the stucco houses of Lynnhurst and Tangletown, the vent run may cross half the basement, turn twice and pass through an old rim joist before it reaches daylight. Lint collects at every turn of that pipe. When air cannot leave, heat builds in the drum, the high-limit thermostat starts cycling, and a load that should take one cycle takes two. Leave it long enough and the thermal fuse opens, which shuts the dryer down until the vent and the fuse are both dealt with.
Gas and electric dryers share a drum, belt, rollers and thermostats, but they make heat differently, and that decides what fails. Electric dryers use a coiled heating element that can break, often after months of running against a restricted vent. Gas dryers light a burner with a glowing igniter and open the gas with a pair of valve coils, and the coils weaken with age so the flame lights, goes out and refuses to come back. Both types wear out drum rollers and belts, which shows up as a thump, a squeal or a drum that will not turn. Here is a common one near Minnehaha Parkway: a gas dryer tumbles but blows cold air. The igniter glows, the flame never appears, and the meter finds the valve coils out of range.
