From the maker's and parts sellers' listings for this number. Compare them with the label on your old part.
How This Relay Works
A relay is a small switch run by a low voltage coil. When the system calls for operation, voltage energizes the coil to change the state of the switch contacts.
This design lets low voltage controls switch power to other parts without carrying the main load through the control board. Moving parts and contacts can wear over time, which can cause the relay to stop switching properly.
Understanding the Specs
When you check an old part against the Ice O Matic 9101083-01, you must match the physical size and pole configuration.
The listed dimensions and contact layout for this part include:
- Poles: 2
- Height: 1.05 in / 2.67 cm
- Length: 2.65 in / 6.73 cm
- Width: 1.3 in / 3.30 cm
How to Confirm a Match
Relays must match their electrical ratings and contact styles to run safely. Installing a relay with the wrong coil voltage or contact arrangement can damage the equipment.
Use these match rules to confirm your part matches:
- Coil volts: must be the same
- Action: same contacts, like SPDT or DPDT
- Amps or delay: same or higher rating, same delay
- Poles: must match the 2 poles on this part
Steps for Safe Replacement
Always take your time when replacing electrical relays. Swapping wires incorrectly can cause system faults or short circuits.
- Turn off power at the breaker.
- Test for power with a meter to verify the circuit is dead before touching anything.
- Take a photo of every wire and terminal connection on the old relay.
- Disconnect the old relay and remove it from its mounting location.
- Mount the replacement relay in place.
- Move wires one at a time to the matching spots on the new part.
- Restore power at the breaker and test the equipment.
Read your old part
- Locate the part number printed on the housing of your old relay.
- Check that the label reads 9101083-01.
- Verify that the old relay uses 2 poles.
- Measure the old part to confirm it matches the length of 2.65 in / 6.73 cm, width of 1.3 in / 3.30 cm, and height of 1.05 in / 2.67 cm.
When to call a pro
Hire a licensed HVAC technician for any step you are not sure you can do safely. If you cannot confirm power is off, see damaged wiring, or feel unsure about reading wiring diagrams, stop and call a professional.
Questions
What does a relay do in an ice machine?
A relay is a small switch run by a low voltage coil. It opens or closes contacts to direct power to machine components when signaled by the controls.
What does the 2 pole rating mean for this relay?
A 2 pole relay controls two separate electrical circuits or contact sets at the same time. The replacement must have the same number of poles to handle the existing wiring.
What rules must I follow when matching a replacement relay?
The coil volts must be the same as the original part. The switch action must provide the same contacts, such as SPDT or DPDT. The amps or delay must have the same or higher rating and the same delay.
How can I avoid mixing up the wires during installation?
Take a photo of every wire before you remove the old relay. Then move wires one at a time to the same spots on the new part.
