Question about U-Line Icemaker

U-Line BI-45A won't run

My BI-45A was running but not making ice. I discovered that the fan motor was running very slow so I replaced it. Now neither the compressor nor the fan run. I know that I have power to the unit because when I manually advance the ejector, it completes the cycle - including adding water - but the compressor and the fan never start up. Is there something I need to reset ? Is there some other part than I need to replace ?

Thank you.

    Thanks, drcool299. I could not find any loose or disconnected wires. I used my ohmmeter to check the thermostat and it showed an open circuit across the two two terminals that have wires connected to them - regardless of the position I put the thermostat control in. So that looks like it might be the problem. I am confused, however, that it should go out right at the time that I replaced the fan motor. That seems too weird to be a coincidence. Any thoughts as to how this could have happened ? I would like to have some more assurance before I shell out the money for this additional part. I did some checking on-line and it looks like a thermostat for the BI-45A will run me 45-50 USD. Any further thoughts you might have would sure be appreciated. Thank you.

    drcool299: Well, your very first suggestion to me was right on target. In the process of checking the status of the thermostat and the new fan motor, I discovered that a connection to the thermostat had come loose - most likely while I was removing the old fan motor. This connection powers the compressor and the fan. I put it back on and both of those components now work. That is the good news,

    The bad news is that I am back where I started - except with a new fan (motor and blades). The fan and the compressor run, but the system does not cycle and it does not cool. What advise do you have for me now ? Thanks,

Check the wiring diagram at the back panel. trace each component.

you could have disconnected one or two wires while replacing the fan, check the thermostat control. see if there is continuity. check the wirings also that went there.

tnx 4 using fixya,

    unless you put a shorted fan motor. that could break the contacts of the thermostat.
    try to jump first the thermostat leads just to be sure that there is no shorted part that would ruin a new thermostat. check if everything would run ok and seeif it would freeze and make some ice.

    if everything works fine, then replace the thermostat.

    tnx again, please don't forget to rate me.

    i don'r know if you have a gauge manifold. the tool that can measure the pressure of the system,

    i would like you to measure the amount of refrigerant in the system while running.

    you could have a leak and the gas leaked out and there is no DIY in case of refrigerant leak

    try to look all over the lines, evaporator, condenser, any refrigerant line and look for oil stain. that would be your leak.

    you have to bring it to a tech for repair.

    hey, tnx 4 the rating. i appreciate it.

You can have a couple of things causing this. First do you see flakes in the ice cubes? Yes replace the icemaker. No then I would remove the cover off the icemaker (pry on the corners and pull) Check to see if the motor gears is rusty. If yes then its causing the motor to run slow and overfillilg the icemaker. You can also check to make sure the fill tube is pointing downward in the water cup of the icemaker. If that looks goo then it cold be the matter of replaceing the faceplate of the icemaker. That would replace the switch, motor and gears.

Will not get cold. the compressor isrunning all the time and will not make ICE. It has a brand new ice maker unit in it, thermostat, and watervalve from last year.

A BI 95 will run until the thermostat is satisfied. The it closes contacts between red and yellow to advance icemaker. Make sure thermostat is set at a warmer temperature. 10-15 degrees is what your looking for in the bucket. After you turn it down and it doesnt cycle then make sure it wires right. Red terminal 1 yellow terminal 2 blue/black terminal3 Or it could be to warm (heavy frost needs defrosting) If everything is running and not cooling then a sealed system is expected. Also make sure you have the right icemaker if not then that could cause everything. Sensor needs to be in the tube about 12 inches.

Can you tell me the model? If its a bi series then it should make ice every 45 min. temps should be 10-15 degrees in bucket. If its a combo then it could take 24 hours to make 1/2 of the bucket.Should be the same temp in your bucket.Make sure you dont have heavy frost in the freezer, Make sure the condenser fan is running and clean.If the temperature in freezer is alot warmer than this and everythng is running then it could be a leak in the system. If its colder than that then set the thermostat to a warmer temperature

Your unit will only harvest when your thermostat is satisfied. If you have heavy frost you need to defrost the unit. If no frost then make sure the fan is running by the compressor. If the fan isnt running then the compressor is going off on overload. Or it could be the fan running but the compressor is not. If thats the case you will need a service tech.

Our old RV U-Line Icemaker, model 45A has stopped making ice and does not get cold. What does it need?

You need to check to see if the compressor is running and the fan is running. If both are then you need a new unit. The 45A has the r12 refrigerant in it and you wont be able to get parts for a r12 system. U-line makes a BI95 to replace that model. If the fan isnt running then I would replace the fan. If nothing is running then it could be a bad thermostat but first make sure the ejector blade on the icemaker is at the 12 oclock position.

Uline icemaker compressor runs very hot - slow ice production

if the ice production is slow first try to set it on a warmer temperature. Now if its frosted up then you will need to defrost it. Also check the fan to see if its running. if yes is the condensor clean? If yes then check temperature in bucket. 10 to 15 degrees is ideal for this model.

Give-me plis a wiring digram manual of the Ice Maker U-Line BI-95

Your going to call U-line and ask for it. 800-779-2547. Now what are you trying to do? I can give you the wires on the thermostat. Terminal 1 is red(icemaker) Terminal 2 is yellow(common) Terminal 3 is blue/black(compressor and cond fan motor) When yellow and blue or black are closed this will run the compressor and fan.Thermostat is satisfied then the red and yellow are closed and it advances the icemaker. Ejector blade at the 12 oclock calls for freeze cycle. at 2 calls for heater to come on(inside icamaker) at 10 oclock it trios the water switch and calls for water.Then back at 12 oclock calls for freeze cycle. Temps should be 10-15 degrees in the bucket. Warmer the setting the more ice it makes.
