Dryer repair guides for no-heat, long cycles, and error codes. Covers gas and electric models, vent safety, and thermal fuse diagnosis.
A dryer that takes two cycles to dry a load or shuts off mid-cycle is more than an inconvenience — it wastes energy, wears out clothes faster, and in the case of gas dryers, can signal a safety hazard. Our troubleshooting guides start with the most statistically likely cause for each symptom: no heat is a thermal fuse 60% of the time, long dry times point to a blocked vent in 70% of service calls, and a drum that tumbles but produces no warmth usually means a failed heating element or gas valve coil.
We break down diagnosis separately for gas and electric dryers because the repair process differs at every step. Gas dryers require igniter and flame sensor testing with a multimeter, while electric dryers need element continuity checks and high-limit thermostat diagnosis. Each guide includes the specific resistance readings you should expect and the exact replacement part numbers for the five most common models we service in the Sacramento and Bay Area markets.
Dryer venting deserves its own section in every guide because lint-clogged vents cause an estimated 2,900 house fires per year in the US. California building codes require rigid metal ducts (not foil flex) for new installations, and our maintenance guides walk you through a full vent inspection with the tools most homeowners already own.
