Ultrafryer 18A333 Relay

What This Relay Does

A relay uses an electromagnetic coil to move internal electrical contacts. When the control circuit sends voltage to the coil, it pulls the switch contacts closed or opens them, depending on the design.

This lets a low voltage control signal switch power to heavier loads safely. Because it handles electrical switching, a worn relay can prevent connected components from turning on or shutting off when called.

Understanding the Part Specs

Matching the physical size and electrical ratings of a relay is critical for proper operation and fit in the cabinet.

• Voltage: 24V coil rating
• Height: 2 In
• Length: 2 In
• Width: 2 In

Confirming a Replacement Match

When you need to match a relay, always check the physical label on your existing part. For relays, key rules apply:

Coil volts must be the same as your original unit. The action must feature the same contacts, such as SPDT or DPDT. The amps or delay must feature the same or a higher rating, along with the same delay if a timer is present.

How to Replace It Safely

Swapping a relay involves line-level or low-voltage control wiring. Work methodically to avoid wiring errors.

1. Turn off power to the unit at the main breaker panel.
2. Test for power at the unit to make sure the electrical supply is completely dead.
3. Take a clear photo of every wire and terminal connection before removing anything.
4. Move wires one at a time from the old relay to the exact same spots on the replacement relay.
5. Mount the new relay securely in place and restore power to test operation.

Read your old part

1. Locate the part label printed on the side or top of your existing relay.
2. Check that the part number shows 18A333.
3. Verify that the coil voltage rating printed on the label states 24V.
4. Measure the old part to ensure it matches the 2 In length, 2 In width, and 2 In height so it fits the mounting space.
5. Confirm the contact type and terminal layout match your current wiring setup.
