20 Most Recent White Rodgers 0754-1 Electric Water Heater Control Questions & Answers

Yes, Set the right side to 74 and you should feel cool air from vent Give it 15-30 minutes and chk to see if left side drops. If it has a preset at a certain time it will default to the preset if its in that time period and is shut off. Make sure it is set on cool. 84 is hi and is normally set there by managers to cut costs.

Sounds to me you are low on freon and the evap coil in icing up

hello cwest.... If your thermostat is reading Celsius instead of Fahrenheit press the 'Set Time' & 'Hold Temp' buttons at the same time to toggle it back to read Fahrenheit again.

You have 240Volt electric water heater.
Lower thermostat is set as low as it can go at 77.
But you want water temperature set to 66?
First thing to remember is that water heater thermostat settings are approximate since they read temperatures through the steel tank wall.
Second thing is that thermostats for electric water heater are generic, and are not made for lower temperature range settings. This is probably since most people complain that water is not hot enough.
I'm looking at a generic lower thermostat from Lowes right now. The low temperature setting is 90 degrees F.
Looking at some older thermostats from a drawer right now: one does not have a lower temperature mark, the other is a Reliance with low temp of 95, the old craftmaster goes down to 80.
So I don't even have a thermostat that goes as low as the one you have, except for gas water heater thermostats that traditionally can be set to 50 degrees for vacation mode to prevent freezing.
More thermostats can be seen on following link:

I'm not quite sure I understand what you have done but, make sure your compresor(outside is running and, that you don't have the thermostat set to "fan". You want the display to show "cool" and then adjust your temp. It sounds like you have the system set to fan and not cool. Provide me with a model number and I will see about getting you a manual.

you need a new thermalcoupling.

this sounds like a short circuit that the cover is making with something. Take a close look at the contacts, wires and how close the cover comes to them.

Sounds like the thremostat is going bad and not functioning right thats why you reseting it so much and then it works. They are not to expensive to replace just write down info of water heater or take old one with you to store

The red button at the middle is the manual reset button.

This item is a buy -out from Thermodisc send a inquiry to there contact us.

Of course turn the power off.I would use a large screwdriver to pry/release the spring clip on either side of control and snap the new one back in.

Gas or electric?

This manual provides specifications of the timers and contacts, and a description of the 3 types of contacts. http://s3.supplyhouse.com/product_files/White%20Rodgers%20-%2024A34-6%20-%20Install%20Instructions.pdf

http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html#Intellivent

1) Typical instructions for Kenmore and AO Smith water heater with Intelli-vent say:
Set on-off switch to ON position.
Hold down both arrow buttons for 1 second.
Then press hotter button.

2) Also check that 120Volt electrical outlet has power, and check outlet with cheap circuit analyzer from home center.
3) If Intelli-vent gas valve thermostat is malfunctioning, and won't reset, then contact manufacturer of water heater for replacement gas valve.
Label on side of tank will have Model number, manufacturer, type of gas LP NG, serial number for part ordering.

follow this steps and fix it. God bless youTroubleshoot a thermostat:

1. Shut off power to the heater at the electric panel and post a sign warning others not to turn it on.
2. Unscrew and remove the electric water heater access panel.
3. Using a small screwdriver, turn the thermostat dial counterclockwise to lower the temperature, or clockwise to raise it. If the water heater doesn't maintain the proper temperature, test the thermostat.
4. Disconnect one wire to the upper thermostat to test it. Set a multimeter to RX1 (resistance times 1) and touch a probe to the thermostat terminals as indicated in the owner's manual. Depending on the model and the terminals tested, the tester should show infinity ( open) or about 0 ( closed).
5. Test the lower thermostat in the same manner.
6. If necessary, replace the thermostat. Unscrew it from its mounting and install one of the same model, size, and rating. Once you install it, adjust the thermostat following instructions in your owner's manual.

Test and replace a heating element:

1. Turn off power at the electric panel and post a sign warning others not to turn it on.
2. Remove the access panel on the electric water heater.
3. Disconnect one of the element wires and set a multimeter to RX1000 (resistance times 1,000). Touch one probe to an element mounting bolt and the other to each element terminal screw, in turn. If the tester displays anything but infinity ( open circuit), replace the element.
4. If necessary, set the multimeter to RX1 and touch the probes to the terminal screws. If there is any resistance reading at all ( closed circuit), then the element is good. If not, replace it. Both upper and lower elements are tested in the same manner.
5. To remove the element, first drain the heater.
6. Disconnect the remaining element wire. Remove the mounting bolts holding the element in place. Remove the element.
7. Replace the heating element with one of the same model, shape, and rating. Make sure you also replace any installation gaskets.

Test and replace a high-limit cutoff:

1. Disconnect power to the heater at the electric panel and post a sign warning others not to turn it on.
2. Remove the upper access panel and push the reset button.
3. Replace the access panel and turn the power back on. If the water is hot, the reset was the problem. If not, you'll need to turn the power off again and reopen the access panel.
4. Use a multimeter to test the cutoff terminals for continuity. If faulty, replace with an exact replacement part.

Change the batteries.
