Beeping coming from freezer

Change the circuit board.

Have seen that on certain controllers before. Very possible your temp. sensor is open circuit or out of spec. or not making proper contact on the wiring harness. You would need a digital thermometer to check the sensor.

It sounds like this is a a non DIY issue. there is really not much you personally can do.

The 3 beeps indicates that the unit was in the freeze cycle for 60 minutes. Causes: 1.) Water valve leaking, allowing water to continually enter the system. 2.) Float switch stuck, sending false signal to board. This indicates ice not being produced. 3,.) Low freon level causing long freeze cycle. 4.) Hot gas valve leaking thru causing warmer than normal evap plates=low production. 5.) Expansion Valve not feeding freon properly to evap plates.
Items 1 and 2 are the most common. Number 3 possible due to freon leak in the system. Number 4 and 5 are usually a very rare occurance.
Hope this helps ya.

try unplugging the unit and waiting 2-3 minutes to allow the electronic ontrol to reset. I am assuming that the temps are normal. peyton

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!

I have a Hoshizaki KM-250BAF that is making 3 beeps then pauses and them makes 3 beeps again. If I unplug the ice maker and plug it in it continues to make the 3 beeps. The manual does not mention anything about beeps. Can anyone help?

the beeping is a fault code i need to know how many beeps it does before it starts over Also you can shut down the pwr this will reset it but if you dont fix the fault it will return

First make sure you have a good 9v battery installed. If it is ok then the problem will probably be in the display board or the wiring connectors between the boards. CE is communication error. If your model has the electronic tempature control instead of mechanical thermostat the problem could be in there. My bet is a bad connection at display board.
