It is probable that if you have something in the heat circuit that steals voltage, this E2 will be coded. The first step is to determine whether or not 24V is present. Then, if 24v is present during a heat call, this is done at the W and C terminals. Do you want to give it a shot on your own? That's fine, but let me give you some help.
The next thing you need to do is check the wiring at both the panel and the load end. Make sure that there are no broken or frayed wires anywhere in the system. If you find a problem wire, replace it with one of equal length from another part of the system. You should also check each conductor within the cable itself for damage. If any part of it feels warm to the touch, then it needs to be replaced.
Finally, make sure that the carrier isn't stuck in the on position. To do this, turn it off completely, then try again. If this doesn't work, then there may be a problem with the switch itself. Contact a qualified technician if you feel uncomfortable trying this task yourself.
Hopefully we were able to help! If you have any other questions about electrical systems, please don't hesitate to ask.
E1 error code on a sensor on a Carrier thermostat The E1 code indicates that the sensor in the thermostat is shorted or faulty. Coding, Thermostat Error Code: E1, enter the building through the front entrance; call the main number for assistance.
In addition to these thermostats, other makes and models may have different codes, so it's best to contact the manufacturer for assistance.
Shorting or malfunction of a thermostat sensor will cause the thermostat to stop sending signals to the furnace, which prevents it from turning on. If this happens during freezing weather, you could be forced out of your home.
Sensor failures are usually caused by dust getting inside the unit and blocking its ability to sense heat. This can happen if a window has been closed all day, allowing dust into the room. When you open the window the next morning, the sensor will detect this change and trigger an energy-saving mode until you turn off the system.
If you are experiencing noise when you switch modes, this means that there is something wrong with the transformer powering the module that changes the temperature. This should only occur with the system turned off. Call our office for assistance.
When the weapon detects that the date or time is incorrect, the E2 error is shown on the CID. This can happen if the device's battery has been removed for a long length of time or if the device has not been connected to Evidence Sync for an extended period of time. Before you start working on any case evidence, make sure that you set your clock correctly. The last thing you want is for the time to be off while you're trying to follow a specific date or time reference found at the scene of the crime.
Here are some common causes of E2 errors:
The battery in the device has expired. Replace it immediately before you begin investigating cases. If the battery was not removed for storage then there is no need to replace it. However, if it has been removed for longer than 24 hours then it should be replaced before continuing with your investigation.
The device was not connected to Evidence Sync. Connect it before beginning your investigation.
The calendar on the device is incorrectly set. Set it before beginning your investigation.
These items are listed as potential sources of error because they may cause the E2 error even though they are not the actual reason.
For example, if the battery was stored outside and gets wet when it rains then it could cause the E2 error even though this is not how the error was generated.
