Do you have to drain the water heater to change the thermostat?
Always disconnect the power or shut off the breaker before doing any work on a water heater. To change thermostats, you will need to remove the access panel and safety cover (do this for both upper and lower access panels on dual element units).
How much does it cost to replace a water heater thermostat?
The average thermostat replacement cost is between $100 and $300. Most other repairs are equally affordable. There are two main types: gas and electric. A gas unit works by way of a gas flame while an electric one works using electric elements, or coils.
How do I reset my water heater thermostat?
Somewhere on your electric water heater, you’ll find a reset button. It’s usually red and often located near the thermostat. It may also be hidden behind a removable metal panel on the unit—and then behind some insulation. Once you find the button, push and release it.
What causes a water heater thermostat to burn up?
Re: What causes burned wires on electric water heater thermostat? A shorted element, depending on WHERE it is shorted, would either cause the water to overheat and trip the ECO, or trip the circuit breaker, but NOT “overload” the thermostat or its connections.
Why does a water heater thermostat trip?
One common thermostat problem with electric water heaters occurs when the lower thermostat becomes “stuck” in the ON position and doesn’t cycle the lower element off properly. When this happens, heat builds up in the upper portion of the storage tank, which will eventually trip the reset button.
Are hot water heater thermostats universal?
No, all water heater thermostats are not universal. There are some variances in thermostats between single-element water heaters and dual-element water heaters. Also, there is a difference in the upper and lower thermostats in dual-element water heaters. Common residential dual-element water heaters are 240 volts.
How long should a hot water thermostat last?
Traditional hot water cylinders: 8-12 years. Heat Pump water heaters: 10+ years.
What is the most common problem with water heaters?

How do I know if my thermostat is working properly?
When a thermostat is working properly, it should display an accurate temperature of what it feels like inside your home. But if the room feels much hotter or colder than the display temperature, that means your thermostat can’t accurately measure the room’s temperature.
How do I know if my thermostat is low?
Test the lower portion of the thermostat, by touching one lead to the common terminal (next to the temperature setting) and the second lead to the left heating element terminal. If the water in the tank is below the thermostat’s set temperature, the multimeter should read close to zero ohms of resistance.
What trips the reset button on a hot water heater?
If a water heater reset button keeps tripping, the first area to inspect is the thermostat. With an electric water heater, you have two thermostats; one upper thermostat and one lower one. When this happens, the thermostat may never turn off the heating element, which causes the reset button to trip.

How do I know if my water heater element is burnt out?
Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.
Why does my hot water heater smell like it’s burning?
Older water heaters can accumulate dust, dirt, and grime. If dust or debris contacts a warm part of the machine, you may notice a burning smell. This is usually an easy fix. Shut down your water heater if it’s too hot to the touch.
How many thermostats are in a hot water heater?
Most electric water heaters above 20 gallons have two thermostats that sense the temperature of the water in both the top and bottom of the tank. The upper thermostat is the boss and always tells the lower thermostat what to do.
