Frigidaire electric dryer runs but does not heat; display shows E5B.

Safety First: Unplug the dryer and turn off the breaker. For electric models, verify both legs of the 240V supply are off.

• Verify power supply:
  • Check the double-pole breaker; reset if tripped.
  • Use a multimeter at the outlet to confirm ~240V across the two hot legs.
• Access heater assembly:
  • Remove the rear panel to access the heater housing on most Frigidaire electric dryers.
  • Visually inspect the heating element for breaks or burn spots.
• Test heating element:
  • Disconnect the element leads.
  • Measure resistance across the element terminals; an open reading indicates a failed element.
• Check thermostats and thermal limiter:
  • Locate the high-limit thermostat and thermal limiter on the heater housing.
  • Test each for continuity; replace any that are open.
• Inspect wiring and control board:
  • Look for burnt connectors or wires at the heater and on the main control board heater relay.
  • Repair or replace damaged wiring and connectors.
• Replace failed parts:
  • Install a new OEM heating element and any failed thermostats or fuses.
  • Reassemble and test on a timed high-heat cycle.
