Midea air conditioner error codes. Indoor unit error code explanation: R series: ... E1, Indoor / outdoor units communication protection. E2, Zero-crossing signal error ... E4, Outdoor unit temp. sensor or connector of temp. sensor is defective.
The E1 code is an error code that appears on the LED temperature display of some digital air conditioners. The error code could mean anything from dirty air filters to a damaged room thermistor, a safety connected to your thermostat that detects room temperature. Troubleshooting the cause of this error code may improve your air conditioner's performance
Other forums say the E1 code is because the AC thinks a button is stuck
or because it's dirty, but almost all of them say to use the remote and
it'll work ok.
If you have the remote, that should still work..if you need to reset it.
If you do not have the remote, believe it or not, some VCR/DVD remotes
will work the system. The remote is a 'One For All' URC-3021B00
The buttons are as follows:
pause= timer on/off
