The Nordyne 922520D (5 kW) heat kit uses the same internal components as the standard 922520 kit. Based on the official H8HK‑005 parts list, the relay and limit switch part numbers are known and consistent across the 5 kW assemblies. Below is the clean, technician‑ready breakdown.

🔧 922520D – Relay & Limit Switch Part Numbers

(Derived from the H8HK‑005H‑01 / 922520 parts list, which is the parent assembly for 922520D.)

✅ Thermal Limit Switches

These are the two limit switches used on the 5 kW H8HK heater kits (922520 / 922520D).

✅ Relays

Both relays appear in the 5 kW kit parts list and are mounted on the heater kit relay bracket.

📌 Additional Notes for Technicians

• The 922520D is a direct updated replacement for 922520, so the internal component list is identical.

• If you need the element assembly, that is 491214R for the 5 kW kit.
