Midea 50 Pint with pump trouble shooting
I bought a Midea 50-pint dehumidifier with pump from Home Depot. I followed the setup instructions and chose it over the comparable Hisense because it seemed like the better fit for my needs.
On initial startup, the fan wouldn't run. The compressor would turn on briefly, then shut off, but the fan never started. As a last resort, I manually spun the fan, and it began running under its own power. Since then, the fan has continued to start normally.
The other issue was that the compressor would only run for about a minute before shutting off very abruptly, enough to shake the entire unit. Given how humid our house is, I expected it to run almost continuously.
ETA: I want to leave this post up for anyone troubleshooting the same issue in the future. It appears the unit was stuck in some sort of initialization or protective state. What fixed it was unplugging the unit, deleting it from the app, and then holding the power button for about a minute to completely discharge any remaining power. That was evidently all it needed. It's now been running continuously for over an hour, and the intake/exhaust airflow and compressor operation appear to be normal.
