It means the trailer is too warm for the thermostat to work - above 90 degrees inside. Take some ice and put in ziplock bag - place over thermostat and cool it down. Unit will start working when thermostat senses it is BELOW 90 degrees. FAULTY DESIGN.

SOURCE: I have a TCL split system air conditioner with error code E2

I have the same problem with my TCL unit. I have had the Tech out to day and I am told it is an internal senor in the unit that fails. I am informed by the tech that this is a very common fault with the TCL unit. Also if you live in Australia like me prepare yourself for a fight with TCL due to them not liking to honour the 5 year warranty. I would not recommend this product to anyone

the e2 error on your thermostat is a problem with the return temp sensor on your system, the only thing you can really do is call a company and replace it, you can't bypass it or remove it cause the system wont run properly

SOURCE: My Heat will not work

the e2 code on a carrier comfort zone thermostat is indicitive of the external safety sensors which are located on your units ductwork in the attic. the e2 code are the hpt/ and lat sensor codes. the hpt is the heat pump temperature sensor and the lat is the leaving air temperature sensor. you can pull off the cover of the panel and behind it will actually give you all the fault codes associated with you carrier tsat.each sensor has a certain ohm rating and if its out of the range it will fail. now as to the reasons for failure, the indoor coil could be dirty, filters dirty, refrigerant charge incorrect.

Error code e2 on Rheem tankless water heater


e2 is not shown among common error codes:
Error e2 might be: Brownout condition or too low of voltage to thermostat. Double check wiring and check for 24 vac between R and C. E2 will clear 15 sec after proper voltage is restored.

Before calling service technician, open following link for Rheem troubleshoot resources including Rheem chat and typical generic manuals and common error codes:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Model number and serial number are required for Rheem contact, and then they tell you what error code means without saying how to fix it, and then tell you to call service technician.

Tankless water heater manuals each say to have qualified technician perform yearly service. Most causes for common error codes are covered by yearly service.

Yearly service is fairly standard in the HVAC and water heater industry with advancement of high-tech 'energy' saving appliances. Of course all costs are energy, and the service call probably costs more that the 'energy' saved by energy-saving appliance. But with high tech stuff like tankless, it is good to have a reliable service guy who knows your machine.

Dryer will not start display works, when i push the start button it just beeps and does nothing, shows a E01 code.


Hi, this is what the error code means,

E1 or E2 Thermistor Failure The dryer will not operate if the exhaust temperature drops below 18 degrees F. or exceeds 250 degrees F.

When the thermistor circuit is open (>50K ohms), the error code E1 flashes in the display.

When the thermistor circuit is shorted (<500 ohms), the error code E2 flashes in the display.

Normal thermistor resistance values:
60 degrees F. - 15.3K ohms.
70 degrees F. - 11.9K ohms.
80 degrees F. - 9.2K ohms.
Hope it helps.
