3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > 60 minutes.
Yellow LED marked 60 MIN energizes.
Check for F/S stuck closed (up), WV leaking by, HGV leaking by, TXV not feeding
properly, low charge, or inefficient compressor.

signal means freeze cycle is longer than 60 minutes. Look for: stuck float, water valve leaking water into the sump, Hot Gas Valve leaking hot gas into the cold side of the refrigeration system. Start there.

Beeping 3 times every 3 seconds


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.

Beeping Ice Machine


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?

This is probably the defrost cycle. The beeps are the high temp alarm. It is probably overly sensitive.
