grounded connection on unit.

it gets rid of condensate by a slinger ring on fan motor throws it up on condensor and evaporates it.

Hi,If you have a slide out chassis then slide the unit out and the drain will be in the back corner of the pan...you can then easily see it and get it open...If it does not slide out then look in the back corners for a hole and use a wire to get the hole open...DO NOT run a drill up in there, you will drill a hole in the coil!!! I have fix a few of those..:-)heatman101

Hello, if there is no drain hole under the unit then it uses the fan blade to sling water on the condenser to evaporate the condensate. Some window units are made this way instaed of using a drain hole.

Hi, this hissing you hear is the head pressure getting very high in the system due to the out door coil is very dirty. It shuts the compressor down until it cools off again, then repeats its self again. Take a water hose and wash down the outdoor coil being careful not to flatten the aluminum fins. This will solve your problem! Good luck,

A Power Reset will fix most things. Turn off the power at the breaker for a couple of hours. It resets the main board and all the relays. Service Manuals in the link https://www.google.com/search?q=Friedrich+Model+MR36TQY3JMA+mini+split+blinking+codes ..

That's what happens with loose electric connections. Need to go from the breaker to the AC unit power run inspecting each wire splice, all electric connections need to be clean and tight.
A loose connection becomes electrical resistance and electrical resistance consumes power, power consumed is dissipated as heat. Overheated, charred, discolored connections can be cut off and reconnected when found.
Start by tightening the circuit breaker wires, and neutral if any.
