Bests & Worsts Reviews from Amazon

The item was perfect. IMPORTANT FOR ALL WHO DON'T HAVE HOT WATER. Fill a cereal bowl halfway full of tap water, unplug the two spade connectors from the sensor, and place them on opposite sides of the water in the bowl. Turn the heat dial down to low. Turn the power switch to off and wait 30 seconds. Turn the power on and cycle the temperature switch from low to hot 5 times ending on hot. The heater will then resume giving you hot water. The sensor has a resistance of about 10-50 kOhms when it has not been exposed to natural gas or splashed with water during cleaning. Most people don't have a 30 kOhm resistor at home to use as a temporary fix. This is fast, easy, and free. You won't get electrocuted. It worked great while I waited for a replacement. I am a cardiac electrophysiologist with an MD and a PhD (the latter in physiology and biophysics). Another customer described using a resistor to fool this safety circuit. Tap water mimics the same resistance of the sensor. This works anytime, day or night.
