Question about Refrigerators

Open Question

Someone told me you could maybe give me pointers to check. I could also send a video to you of the failed startup sequence. Hoshizaki kml-250mah Ice Machine Problem. I had someone clean the ice machine and every time it leads to a service call I just can't afford. I get two a beep error. Now I replaced the filter, here's what happens. I turn on. I see a red light and a series of green. On the third green I hear a hiss of a release valve, water starts to circulate, the fan and unit starts and then stops in about 15 seconds and goes into two beeps. It seems the amount of water circulating is slow as if not enough water is available which is why I replaced the filter. Before cleaning it worked like a charm so I don't buy bad compressor, valve et cetera. Now last time someone damaged a device that measures temperature and tells the unit when to stop making ice. I learned that if this goes bad, which it often does because it's a delicate part that you can jumper the two leads where it connects and it bypasses the part. I did this. Same problem. The person who cleaned it did take out the tray that guides the ice that falls into the bin and put it in incorrectly. I found the unit stalled in 2 beep mode because this guide tray was not installed properly and I did see some ice so right after cleaning it did try to produce ice and probably failed due to the backup; unlike now it starts and stops right away. It probably stalled due to the tray being in incorrectly and the ice backed up. The tray is in correctly and the unit has been off for a week. Now, what else should I check? The problem stems from the cleaning and possible backup oh ice that couldn't fall into the bin. Help please.

SOURCE: No ice...different question

Are you able to see if you can push a Q-tip or something up the fill tube line to see if it's frozen up inside there. It happens on certain units. You may need to take the Ice Maker out (easy) to get to the fill tube.

SOURCE: Ice Maker on/off switch has blinking red light, will not produce ice. Manual no help

When you open the freezer door the light should be blinking. When you hold the flipper door shut (on the left hand side) without blocking the beam, the light should stay on solid. If all of this happens then the optics are o.k. If optics are ok then you most likely have a broken motor module on the icemaker and should replace the icemaker thermostat along with it. A bad icemaker thermostat will lead to the module breaking. If you not sure how to replace these parts then I would just replace the whole icemaker. That would be easiest and usually not much more expensive.

SOURCE: Hoshizaki KM-600MAH-E won't start

I don't have a wiring diagram for this machine so I can't be specific, but I may be able to offer a few suggestions. Check for voltage on the coil by slipping the two wires back off their coil connections you should be able to expose enough of the connection to measure voltage. If voltage exists when machine should be filling, you either have a bad coil, or water is not reaching this point. Check coil resistance by removing wires and testing coil. Resistance reading of 0 or O/L (out of range) would be grounds for replacing the coil.
If coil tests good, look for plugged water filters on water line leading to machine.
Hope this helps,

SOURCE: km 500 kae hoshizaki 3 beeps every 4 second compressor not coming on

put an amp probe on common wire at compressor and see what amps are when it tries to start. 40 to 60 is mechancially locked up compressor. kill power and test start and run capacitors. there is an thermal temp over load on the compressor that opens when comp gets hot from trying to start. gently remove and look for cracks or burned looking. . i saw one this week doing exact same and i have ordered the oem compressor start cap realy and run cap and drier and will put in all new gas. be sure to allow sufficient time when switched to ice for it to get to ref cycle, it may take 5 minutes starting with water purge, then fill, etc. good luck, call hoshizaki dist they are usually pretty helpful if you need a auth service rep in you area. i think they are three years warrantied!

My kml 250mah stopped makinr this condition?g ice after descaling. what is a possible cause fo

The valve that you turn to clean the area in between the plates has a small micro switch. This prevents the compressor from running in cleaning cycle. If the compressor is running, there is another issue.

Something wrong with Harvesting cycle, ICE will not come out, coils freeze up.

If you need answers and have not recieved results I will try to help, I see no one responded to your request because the manual and diagnostics info seems to only be sent to people that sell and purchase the machine. If you need help and want answers  you can call me at 864-812-1887 or e-mail me at  your description of the problems could be many different possibilities. I want to know and help also.
