Parts for Thermador PRD304EHC/04: Pcb's Assy Parts

If your gas burner won't ignite or clicks continuously without lighting, the spark module may have failed. This electronic component generates sparks reliably.

This electronic PC board is the appliance's main control, processing inputs and directing power to components so cycles run correctly. Replacing a failed board can restore normal operation when the unit is dead, won't start, or stops mid-cycle.

• Interprets user inputs and sensor feedback to execute programmed cycles
• Switches relays to power motors, valves, heaters, and other loads as required
• Manages timing, temperature, and safety logic for consistent performance
• Typical failure symptoms: no power/won't start, unresponsive or erratic controls, cycles ending prematurely, recurring error codes

• Disconnect power before servicing; verify power is off with a meter
• Use ESD protection; handle the board by the edges to avoid static damage
• Move connectors one at a time to identical positions on the new board to prevent miswiring
• Some models require service-mode setup or calibration after installation—follow your model's service documentation

Small hardware pin that secures or pivots components in gas ranges and cooktops. Replace if worn, missing, or broken to restore proper alignment.

This cable harness routes power and signals between key components to restore reliable electrical connections and normal appliance operation. Replace a damaged harness to fix intermittent power, control failures, or non-responsive functions. What it does:

• Provides the multi-conductor wiring path that links control boards, sensors, and motors
• Carries low-voltage signals and/or line power needed for normal appliance functions
• Commonly replaced when wires or connectors are damaged, burned, or corroded
• Can resolve symptoms such as intermittent operation, no power to components, or control errors

• Disconnect all power before accessing wiring or controls to avoid shock
• Route harness along original clips and channels to prevent pinching or chafing
• Inspect connectors for damage and replace if terminals are loose or burned
