Either overload and relay or compressor run windings are bad

I have a hotpoint freezer fza34 The red high temp


it could be that your fridge,freezer setting is not turned up high enough to keep the freezer cold enough.turn it up to setting number 5 at least and if that dont do it u could have a faulty thermostat.have it checked by a engineer.

Hi - We've got a Turbo Air TGF-23F mrechandising freezer that freezes - down to -15 and then suddently begins to warm up about 1 degree per minute. In about 15 minutes its just over 0 degrees and...


Did they test the thermostat? I would think that the compressor would kick on before you got that much of a fluctuation, unless the thermostat is not sensing the change fast enough.

The run and start capactiors and relay, did they give you a reason for that? When the compressor kicks on does it surge the power? Light dim or something? It is hard to guess without being able to put an o'scope on your machine to be able to see what it is doing, but just based on what your write-up was, I can't see the parts you said they want to replace will fix the problem.

The freezer is running, and the light is all coming on but it is not freezing the contents in the freezer?


Hi and welcome to FixYa. I am Kelly
If your sure the compressor is running and it is not freezing then there has to be a system coolant leak.
Having said that there are a few things to check:
1. Is the compressor in fact running Y / N
a. Yes = coolant level problem or coolant system blockage
b. Not running = (Possibilites below)
1) PTC / Klixon Thermal overload failure
2) Run capacitor failure
3) Temp control failure
4) Automatic defrost thermostat or thermistor
5) Defrost timer or Adaptive defrost control failure (depending on model)
2. Is the compressor very hot to the touch or room temp?
a. VERY hot = unplug the unit for at least 30 minutes and then plug it back in.
b. ROOM temp = any of the above in 1b items 1) - 5)
3. Is the evaporator fan running?
a. Yes = Temp control is ok Defrost system is probably ok
b. No = same as 2b

With a model number I could pass on a few additional things to do. For the moment use the above.

Thanks for choosing FixYa,

Kelly

I have a Hoshizaki Model KM500MAE that keeps freezing up. What can I do to stop this problem


several things cause freeze ups.
If you have water filters on the water system, be sure they are not restricting the water flow. water flow pressure should not go below 20 psi.
The bin stat may not be shutting off the unit properly. It should shut off machine within 10 seconds of ice making contact.
Make sure the float switch is not dirty. Be careful when cleaning. Fragile
Make sure water pump runs the entire time it is in the freeze cycle.
Be sure the evaps are clean. Ice cubes will hang on if not clean.
Water solenoid has a screen where the water line screws on to it. Turn off water and check screen to be sure it is clean. This can restrict water flow.
Make sure water valve closes all the way. Turn machine off and see if water is still running. Valve may be leaking water thru.
Dip switches on the board, #1 and #2. Turn them both on and it will change the defrost time to 3 minutes. If both are off, they are set on 1 minute.

Hope this solves your problem. Let me know

Avanti chest freezer cf199 will not freeze. A


Sounds like your freezer has lost its charge of refrigerant. That motor sound is the compressor. And the internal thermal overload is tripping it out every minute because refrigerant also cools the compressor motor. Have a licensed repairman find the leak, seal it,and recharge it with R134a refrigerant.

This sounds like a bad thermostadt, since the quick freeze button does work. But it should be much colder than 32 degrees. It may also be the motor, since it runs for brief periods of time after plugging it back in.

I'd say best bet here is to call a repairman. (sorry...)

Hoshizaki ice machine KM500-MAE not sending water to harvest


I would not change the pump. If it runs for 3-5 minutes and stops, it has to be a control. The control board runs the freeze cycle for the first 5 minutes. This prevent "Short Cycling" of the freeze cycle. The board looks at the float after the first 5 minutes for the proper water level but should not effect the pump. If the pump does not run in the wash mode, check out the "Power/ Wash" switch. I would start there before I go spending hundreds on pump motor or control board. You may be able to get by on a $20 fix! Do this and get back to me. We will get it going.

Good Luck

Hoshizaki Ice Machine Model KM-500MAF


(Quated From Hoshizaki Technical Bulletin)
An alarm code of 3 beeps
every 3 seconds means that the control board has shut
down on the 60 minute freeze cycle back up timer.

The “E” control board has a 60 minute timer that starts at
the beginning of the freeze cycle. If the float switch fails
to open and start the next harvest within 60 minutes, the
board will automatically start the harvest cycle. If this
occurs in two consecutive cycles, the control board will
shut the unit down on the manual reset, freeze cycle
back- up timer. The yellow fault LED marked “60 min.”
will illuminate. This safety is designed to help prevent a
freeze up of the evaporator.

Once you have identified the 60 minute alarm, there are
several things to check. Reset the alarm by depressing
the white reset button to the right of the fault LED’s.
This must be done with the power “ON”. Now check the
float switch to see if it is stuck in the up position. A stuck
float can occur if scale is present on the reed switch
shaft inside the housing. To check it, drain the water
reservoir, unplug the black float switch connector (K5)
from the control board and check it with an ohm meter
for a closed switch (zero ohms). If the float switch is
sticking, clean it with ice machine cleaner or replace it as
necessary.
An inlet water valve which is slowly leaking by during the
freeze cycle can cause a 60 minute alarm. If the inlet
water valve is stuck wide open, it is unlikely that any ice
will form on the evaporator. Check for a slow leak by
allowing the unit to cycle into the freeze cycle and
disconnecting the hose at the outlet of the water valve. If
water leaks by during the freeze cycle, the water valve
diaphragm is likely damaged or the small diaphragm bleed
port is clogged with scale. Clean the bleed port or replace
the diaphragm or entire water valve as necessary.

(I Recommend to get a refrigeration tech for this part).

Another possibility is a refrigeration system problem. You
should use normal refrigeration diagnosis procedures to
check for one of these problems. If the thermostatic
expansion valve is not feeding properly or the refrigerant
charge is low, the evaporator will not form ice as it should
and a long freeze cycle will occur. This could also be the
result of the hot gas valve not closing completely during
the freeze cycle or if the compressor valves are weak or
inefficient. An inefficient compressor however, will
usually show up first on the KM model through a longer
than normal harvest cycle. This is because of cooler
than normal discharge gas. Use proper refrigeration
practices to repair a refrigeration system problem.
While these are not the only reasons for a 60 minute
freeze cycle, they are the most common and should be
checked to resolve a 3 beep/yellow fault LED alarm.
