Parts for Frigidaire FTHD18P4KB1: 09 - System Parts

Includes service line.

A wiring harness that routes power and signals between a refrigerator's internal electrical components, helping lights, controls, fans and motors operate correctly. Replacing a damaged harness restores reliable electrical connectivity and reduces risk of intermittent faults. What it does:

• Routes power and signal connections between the control board, lights, motors, sensors and other internal components.
• Common visible issues include frayed insulation, broken or loose connectors, or heat damage at terminals.
• Replacing a faulty harness helps eliminate wiring-related faults that can cause component failures or safety concerns.

• Always disconnect power (unplug appliance or shut off circuit breaker) before inspecting or replacing the harness.
• Match connector shapes and pin counts; route the harness along the original path and avoid tight bends or pinch points.
• Secure with the existing clips or ties; replace damaged clips or protective insulation as needed.

Replaces a failed defrost heater in the freezer section to clear frost from the evaporator coils. Restores normal airflow and temperature recovery when ice buildup causes warm spots, poor cooling, or fan noise from blades hitting frost.

What it does

• Heats the evaporator during defrost to melt accumulated ice.
• Helps prevent airflow blockages that lead to warm fridge temps.
• Reduces heavy frost on coils and around the fan shroud.
• Addresses symptoms like rapid frost return, ice-bound coils, or noisy fan contact.

What’s included
One defrost heater assembly.

Install notes

• Unplug the refrigerator before servicing.
• Access the evaporator cover in the freezer; carefully remove ice as needed to avoid damaging fins.
• Note wire routing/terminal orientation; transfer to the new heater one-for-one.
• After reassembly, run a test cycle and monitor temps once the unit completes a full defrost.

This aluminum strap secures the defrost heater firmly against the evaporator coil to maintain proper contact during defrost. Correct contact improves heat transfer so frost melts evenly and helps prevent recurring ice buildup on the evaporator.
