Frigidaire 5304406099 Dryer Safety Thermostat

Product Description

The FRIGIDAIRE 5304406099 is a dryer safety thermostat designed to monitor and regulate the temperature of a residential electric or gas dryer heating system. When the dryer exceeds its safe operating temperature, the thermostat opens the electrical circuit to cut power to the heating element, preventing damage and reducing fire risk. Once temperatures return to safe levels, the circuit closes and heating resumes. Licensed appliance technicians and qualified service pros install this part as part of routine dryer thermal safety maintenance.

This safety thermostat fits into the thermal control circuit of the dryer, typically mounted near the heating element or exhaust duct. It functions as a protective limit switch within the heating assembly, working alongside other thermal components such as thermal fuses and operating thermostats. It is suited for residential dryer service where the original thermostat has failed, caused nuisance shutdowns, or been identified as faulty during a diagnostic check.

Key Features

• Opens circuit on overtemp condition to shut down the heating element and prevent overheating
• Resets automatically once temperature drops to safe operating range
• Direct OEM replacement part for consistent fit and function
• Compact form factor suited for standard dryer thermal safety mounting locations

Compatibility

Designed as an OEM-style replacement safety thermostat for compatible Frigidaire residential dryer models. Verify fitment against the appliance model number before installation.

Installation Notes

Installation should be performed by a qualified appliance technician. Disconnect power to the dryer at the breaker or unplug the unit completely before beginning any service. For gas dryers, shut off the gas supply valve before accessing internal components. Mount the thermostat in the OEM-specified location and confirm all electrical connections are secure before restoring power.
