Substitute 669470R , LDK-110000-070

LDK‑110000‑070 Ranco/Robertshaw 24V Reversing Valve Coil

The LDK‑110000‑070 is the OEM 24‑volt solenoid coil used on Ranco V‑series 4‑way reversing valves. This epoxy‑encapsulated, moisture‑resistant coil provides the magnetic force needed to shift the pilot valve between heating and cooling modes. Includes a 48" wiring harness. Direct replacement for COL12849, S1‑025‑30215‑001, and 61‑101713‑01.

Features:

• 24V AC continuous‑duty coil

• Epoxy‑encapsulated, moisture‑resistant

• 48" leads with harness

• Red color‑coded housing

• Fits Ranco V0, V1, V2, V3, V6, V10, V12 reversing valves

LDK‑110000‑070 Is

It is a 24V AC solenoid coil for Ranco LDK‑series reversing valves, used in residential and light‑commercial heat pumps.

This coil energizes the pilot valve that shifts the refrigerant flow direction.

🛠️ What It Fits

Designed for Ranco V‑series reversing valves:

• V0, V1, V2, V3, V6, V10, V12

These valves are used in:

• Split‑system heat pumps

• Packaged heat pumps

• Window‑type heat pumps

🔍 Symptoms of a Bad Coil

• Heat pump stuck in cooling or heating

• No “click” or shift when calling for mode change

• Coil ohms open when tested

• Weak magnetic pull → valve chatters or fails to shift

🧰 Technician Testing

• Check continuity across coil leads

• Apply 24VAC and verify magnetic pull at the core
