A GFCI/GFEP (Ground Fault Circuit Interrupter / Ground Fault Equipment Protection) works differently than a circuit breaker by specifically detecting a small imbalance in electrical current between the hot and neutral wires, which indicates a potential ground fault (like a person touching a live wire), and instantly shutting off the power to prevent shock, while a circuit breaker only trips when there's a significant overload in current flow on the circuit, like a short circuit or too many appliances plugged in.
No, a circuit breaker will NOT protect against a power surge; a circuit breakers primary function is to protect against excessive current flow (overload), while a surge protector is specifically designed to handle voltage spikes, which are what power surges are considered to be.
Assure there is power to the timer. If there is power to the timer, then make sure the ON/OFF button is pushed all the way to the right - ON position. If this doesn't resolve the issue, press the RESET button using a paper clip. If none of these steps resolve the issue, then contact WarmlyYours at (800) 875-5285 to order a replacement controller.
The Hardwired Programmable Timer (GK16-30090-0002) supports both temporary and permanent manual control:
- Temporary override — Briefly press the push pad to toggle the towel warmer on or off. The timer will automatically return to its programmed schedule at the next scheduled event, so this is ideal for a one-time exception to your routine.
- Permanent manual mode — Press and hold the push pad for several seconds to lock the device on or off indefinitely, bypassing the schedule until you manually change it again or re-enable automatic mode.
Important: The towel warmer's own built-in on/off switch (located on the unit itself) must be in the ON position for the external timer to work. The timer cannot power a unit whose built-in switch is physically set to off.
For complete instructions, see the "Timer Override" section in the installation and operation manual, available on the Towel Warmer Controls page under Documents & Articles.
GFCI can fail for various reasons, such as wear and tear, moisture, corrosion, power surges, faulty wiring, or improper installation. Some of these causes can be prevented by regular inspection and maintenance, while others may require professional assistance. It is important to note that GFCI devices (ex. thermostat, breakers, outlets) should be tested regularly as these do wear out over time.
