BEFORE YOU CALL A LICENSED PROFESSIONAL, OR FILL IN THE TROUBLESHOOTING FORM:
Fluctuations in temperature are normal in some cases, especially when the temperature outside drops in a short period of time and causes the incoming water temperature to lower. This fluctuation is caused by a wider range of temperature rise (refers to the ground temperature of water) that the heater has to accomplish to accommodate your hot water applications and does not indicate a problem with the heater. The fluctuation will correct itself as the temperature warms if this is the case. Clicking on and off infrequently once or twice a day is normal. There may be one or two ounces of water in the heat exchanger, which the heater senses. Once the heater determines the flow of water, the system shuts off.
