Question about Manitowoc Kitchen Appliances - Others
SOURCE: ice cube cycle time very high
i suspect a defective liquid line or pump down seleonid coil. just make sure you hear the "click" when it starts up if not the selenoid coils could be defective. also verify that the condenser fan is running,because if not you are short-cycling on high head pressure. please contact if you need any additional info

I wouldn't recommend R-134A for an existing unit conversion. The head pressure will probably be a bit high and a complete oil change will be necessary. I don't know what model you have or what the nickel plating on the plate looks like now but an R-12 machine will be pretty old. If you must convert I would use one of the interim replacements for R-12 such as R-414B also known as Hotshot, possibly R-409A, or Frig-12 that was made as a interim for the automotive a/c applications. Not knowing your availability to these various refrigerants I might also recommend checking the automotive a/c replacements to see what is available. As for amounts with such a small system and a TXV metering device I would just add 22oz as long as the head pressure doesn't get over say 175psi during freeze mode.

Hot gas valve needs to be seated to make sure it doesnt leak thru. At times the valve will close but it doesnt seal so it bleeds thru. You will need a hotgas valve replaced.

You're bridge thickness is set to high, lower the bridge on the sensor located when you open the front door behind the water curtain on the top. If the sensor is scaled badly replace it.
