The problem could lie with the thermostat or the heating element. You need to check both with a circiut tester for continuity, this should tell you which is at fault then replace as necessary.

Why does the water suddenly runs COLD after many minutes of running hot?


Unless you are using a tankless hot water heater, there is a limited amount of hot water available in the tank. Electric and gas water tanks need time to recover after use, and if you are using heavily, it can exhaust the available supply. That said, there are a couple reasons why you may have less hot water than seems normal. In both electric and gas water heaters, silt can form in the bottom of the tank. This will build up over time and displace water. It also reduces the heating efficiency of gas units. There is a drain valve on the bottom of water heater tanks to allow for purging of this silt periodically, but few ever do it. You could also have, in the case of an electric hot water heater, a bad element or thermostat. Most electric heaters have an upper and lower element and thermostat. If one fails the other will still work, but the water takes longer to get hot and will deplete faster.

Whirlpool hot water heater puts out overly hot water


1) Make sure factory-supplied insulation and cover are reinstalled over thermostats, or cooler room temperature causes thermostat to under-approximate tank temperature, and this causes overly hot water.

2) Replace both thermostats.
Sticking thermostat can seem to act normally when tested, but when left alone it sticks, causing runaway overheating.

If you have single-handled faucet the faucet cartridge might be bad.
If you have recirculation system, then check valve might be bad.

Running out of hot water I replace both heater coils and still seems like were running out of hot water the top coil has 230 volts going to it but the lower has no volts going to it jeff thanks


Hi,

Only one of the hot water heater elements will have power going to them at a time...
When the water at the top of the tank gets hot then the top thermostat should switch the power to the bottom one... this may not be happening...therefore you are only getting about a thrid of a tank of hot water...

Tankless on demand water heater.


Tankless water heaters normally take a little longer than a regular heater to provide hot water because they have to start and get warmed up. I'm guessing the heater uses a pilot light and that the short amount of hot water when you turn on the tap is hot because when the water is sitting still in the heater the heat from the pilot light is enough to get it hot. The tub faucet will get hot a lot faster than the shower because it lets a lot more water through and empties out the pipes faster than the shower. You could probably speed things up by letting the tub faucet run on completely hot for like 10-15 seconds and then turning on the shower.

Hot Water Heater in 1991 Pace Arrow RV is not working


If you look on the outside of the RV, you will find the vent for the water heater behind and access door. There usually is a drain plug and valve located as well. Generally they will be tucked away under the kitchen sink area with internal access as well. You will need to find where the valve that shuts the water off to the unit is and turn it on. Most times the water heater is either electric or propane. But sometimes they are only propane. Once your find the access door, you will know where the water heater is. You can also contact Fleetwood who makes the Pace Arrow to see if they have any information on your unit. Usually your unit info or trim number will be located on a little plaque right by the entrance to the RV. You will need this when you contact them. Hope this helps.
