Learn how to safely replace a T-Max timer on your tanning bed. Step-by-step guide covers identifying the correct timer, disconnecting power, removing the old unit, and installing the new T-Max G2 3W Timer.

Quick answer

To replace a T-Max timer on your tanning bed, disconnect power, remove the old timer module, install the compatible T-Max G2 3W Timer, and test the system before restoring full operation.

Why replace the timer yourself?

A failing timer can cause sessions to end early or not start at all. Replacing it yourself saves a service call and gets your bed back in use faster. The most common replacement for older ProSun T-Max systems is the T-Max G2 3W Timer, which is a drop-in upgrade for many beds.

What you need to know before starting

The T-Max G2 3W Timer is designed as a configuration option for new orders, not as a standalone replacement part. If you are replacing an existing timer, verify that your bed's wiring harness and control board are compatible with the 3W power rating and 10-minute timer duration. If your bed uses an older T-Max model, you may need an adapter or a different timer module.

Step-by-step replacement guide

Disconnect power: Unplug the tanning bed from the wall outlet and verify the power is off using a non-contact voltage tester. Skipping this step risks electric shock or damage to the control board.
Remove the old timer: Open the control panel or access cover. Locate the T-Max timer module, disconnect the wiring harness, and unscrew the mounting bracket. Note the wire positions for reconnection. Take a photo of the wiring before disconnecting to avoid confusion later.
Install the new T-Max G2 3W Timer: Mount the new timer using the same bracket and screws. Reconnect the wiring harness exactly as the original was wired. Ensure all connections are snug and no wires are pinched. The T-Max G2 3W Timer is a 10-minute timer; if your bed requires a different duration, this timer will not be compatible.
Test the timer: Plug the bed back in and power it on. Set the timer to a short session and verify the bed starts and stops correctly. Check that the timer counts down and the bed shuts off when the session ends. If the timer does not respond, double-check the wiring and ensure the timer is receiving power from the control board.
Close the panel and final check: Once the timer functions correctly, close the control panel cover and secure all screws. Run a full test session to confirm the bed operates normally. Keep the old timer as a spare or for troubleshooting if the new one has issues.
