Ice O Matic 9101170-02 Relay Reference Guide

What the Relay Does

A relay allows a low voltage control circuit to safely manage a higher voltage device. Inside ice machines, small control signals direct heavy-duty components to turn on and off.

When the control board or thermostat sends a signal, the internal coil becomes magnetized. This pulls the electrical contacts shut so line voltage can power the auger motor. When the cycle ends, power to the coil drops, the switch opens, and the motor shuts down safely.

Understanding the Part Specs

Electrical and physical ratings must match the original component so the machine operates correctly and fits securely inside the cabinet.

The 9101170-02 relay carries the following exact measurements and electrical specifications from the manufacturer data:

• Voltage: 230V
• Height: 1.25 in / 3.18 cm
• Length: 2.5 in / 6.35 cm
• Width: 1.3 in / 3.30 cm

Confirming a Matching Relay

A replacement relay must meet the physical space requirements and electrical rules of the existing circuit. Installing a part with incorrect ratings can damage the equipment or cause failure.

Always check the old unit against these core requirements before making a swap:

• Coil volts: must be the same as the original part.
• Action: must have the same contacts, such as SPDT or DPDT.
• Amps or delay: must have the same or higher rating, and the same delay if equipped.

Signs of Failure and Replacement Steps

Relays can fail mechanically or electrically over time. Heavy cycling can cause internal contacts to pit, burn, or stick in one position. A burnt coil will prevent the relay from closing at all, leaving the auger motor without power.

If your old switch has failed, use safe servicing practices to complete the swap:

1. Shut off power to the machine at the main breaker panel.
2. Use a meter to test for power and verify the circuit is dead.
3. Take a clear photo of all connected wires to document their positions.
4. Move wires one at a time to the matching terminals on the replacement relay.
5. Mount the relay firmly in its bracket, close the cabinet, and restore power.

Read your old part

1. Look closely at the housing on your existing part to locate the stamped or printed part number.
2. Check that the label clearly reads 9101170-02.
3. Verify the operating voltage on the old part matches the 230V rating of this part.
4. Check the physical dimensions to ensure it measures 2.5 in long, 1.3 in wide, and 1.25 in high so it fits the mounting bracket.
