    Hotpoint refrigerator defrost problem

    I have worked as a appliance repair tech before and am now doing HVAC. I normally post in the Technical forum.

    I have a Hotpoint refrigerator that I've owned for a few yrs. now.

    Once before the defrost quit working. I checked for a defrost timer and found this unit is controlled by a circuit board in the back. Didn't know how to send it into defrost to check the operation. But was able to determine the heater was bad. I replaced the heater and defrost thermostat.That worked fine a couple of yrs. ago.

    Now my rerigerator is not defrosting again. Probably the same problem. I will check the heater again once I melt all of the ice.

    Any suggestions on how to send it into defrost to check voltage at the heater?

    have been talk to GE. Three yrs ago,They told me it can be advance to defrost cycle,this adaptive defrost control by sensors and the fan running by dc.I have the service manule but still have not told how advance to defrost.

    I defrosted unit. A couple minutes after I turned the unit off the fan came on in low speed. I figure the unit went into defrost mode. Checked voltage at heater, 13v. Heater ohmed at 0. Will p/u another heater and defrost thermostat.

    13v??? Is that the correct voltage??? Not familiar with the newer ones, but I worked on domestics for many years. If that is a glass tube heater, keep your fingers off the tube. Use gloves to install it. If you do not subsequent failures are not far away.
    If you really know how it works, you have an execellent chance of fixin' er up!

    Tomorrow is promised to no one...

    No 13v is not correct. I'll update when I repair it.

    the heater is 120v.If you jump the pins at contacts there is spark that means the heater is ok.
    The fan is dc.and adjust the speed by the adaptive module.
    You can have the service manule at appliance parts co

    I think I'll stick with using my multimeter, thanks.
    I am not new to appliances or HVAC. I just needed some info on how to send this unit into defrost.

    I only posted in this forum cause it's the refrigeration forum. I should have posted this in the technical forum.

    If you have a digital led control you can advance it into defrost. If its just a knob control you have to manualy go to the control board behind the frig and jump out the board. There is a 3 wire connector on there one is a power wire and the others are defrost and refrigeration. Cant remember but i think the brown wire is the defrost circuit.Use a jumper wire from power to defrost (Yes this is the correct way) to engage defrost manualy. I couldnt stand these GE unit...

    This post is old, hopfully you already figured it out.

    I got the heater and defrost terminator in. I was not able to manually send it into defrost. I did try jumping out the Line side to the defrost like
    94blowncobra said but all it did was send power to the heater. It did not send the unit into defrost. Will watch it and see if ice builds up again. But I did take care of one problem. I don't forsee a second problem.
    Geez, this is the second heater in 4 yrs. POS.

    Not familiar with your exact system , but there should be a timer down where the comp is , most of these systems go into defrost every 8 hours or so of comp run time.


    the timer could have a dial on it to advance the timer forward.


    most of these units use the heater element as a neutral

    The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.
