How can I find a wirning diagram for a ice maker that has guit making ice but the pump will run?


Hello;

My name is Peter. I am a retired field service refrigeration technician.

Your Ice machine does not have a wiring diagram. I have repaired many of these.

1.) Are you getting water? If not it is your pump.

2.) Reach in and feel the cold plate. Is it cold? If not you have a refrigerant leak.

3.) The problem may also be within your main control board.

Unless you have a current service contract these units are considered throw-always. It will cost you twice as much, if not more, to repair it than what you purchased it for, assuming you call a service company.

Go into the following website. Plug in the first 5 numbers on your model number and a list of model numbers will appear. Your model number is incorrect.

Select the model number then click on parts and you will get diagrams of your icemaker. Water Filters Lawn Garden Appliance Parts

Commercial freezer stops cooling and goes into delay start mode.


unfortunatly the company has gon out of buisnees and parts available
are kind of hit and miss. As a profesional technician it really frustrating.
I would definitly look at the control side of it. some it could be the relay or digital controller. Good luck hunting the parts down. There are some online parts dealers that still carry some parts. Have your model number
and serial number readily available when ordering.

I have a up right hoshizaki model fh1-AAC unit will not come out of defrost


These machines do not work like you think. The display will show the defrost mode even when in the freeze cycle. After a defrost cycle, the cooling system comes on but the display will not show any temperature numbers until the conditioned space gets to within 15 degrees of where you have it set to cool to. So, if it is set to 0, the box needs to hit 15 degrees before it shows numbers. You have a cooling problem. Several thing can cause this. may need a tech to check.

Kenmore Frost Free Comm. Model #253-23425100 - will not stay cold


Two things:

Either the thermostat has inadvertently been turned up, (too warm) or the gas in the compressor tank is low. If it isn't #1, call a repair tech to replentish the has in your compressor. If that isn't it he will tell you what he thinks it is. Good luck!

My freezer is not cold enough to keep food frozen...


the "e" usually means it has an error. it could be a bad temperature thermistor or a bad control board. the most likely is the board.
i hope you are less then 1 year old as the board can be quite pricey, about 150 bucks.
you could try to unplug the unit for a few minutes and then plug back in and see if the code goes away and returns to the cooling mode.

Frigidaire Upright freezer with Beeping Display


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.
