I have a Maytag PTB1953DR refrigerator, would the timer be shot again?

The timer should last a lot longer than that, but I have received bad ones right out of the box. Depending on model year, the full current of the compressor and the defrost heater are present in the defrost timer contacts. The defrost heater should be checked with a volt-ohm meter if continued icing takes place. The defrost heater will have a positive ohm reading if it is okay. If the meter reads infinity or 0.0 ohms, the heater is bad.

you should read around 25 ohms on your defrost heater if it cks good, you should read 0 ohms on your bimetal if its encased in ice, if your bimetal reads 0 ohms and the heater reads good ohms then replace your defrost control. lmk if u need more help

Refrigerator freezing even when you turn it down

Your refrigerator is freezing due to the unit most likely haveing a defrost issue. This is usually caused by the defrost thermostat, the defrost heater, or the defrost timer or adaptive control having a fault condition. If you remove the rear panel in the rear of the freezer it will give you access to the evaporator coil. Located to one of the side usually clipped onto one of the copper lines you will see a small circular round sensor with two wires coming from it. Unplug the machine and defrost with a hair dryer any ice build up on the evaporator coil. If you have a multimeter you can perform a ohms test to assure that the thermostat is working properly. A defrost thermostat usually has an ohms reading of at least .50 ohms or higher. Located under the evaporator coil is the defrost heater. If you unplug both sides of the heater you can also perform a ohms test with a multimeter which would usually read around 21 ohms or higher. Most often this issue is caused due to the defrost thermostat due to this part being manufactured poorly on most all machines. If you find that you have a positive ohms reading on both these mentioned parts. You would then look at the defrost timer or adaptive control as the part causing the fault condition. I will await your reply and to you testing these first two parts before further posting how to test the defrost timer.
I await your reply,
Thank you,
Rick

What's your problem?water leaking into the refrigerator section. Freezer ices over on normal setting

you have a defrost issue number one in which most likely you need to replace the defrost thermostat or the defrost heater remove the rear panel on the inside rear wall of the freezer. The thermostat is a disc like object with two wires attached to it you can test this by performing an ohms test on this part should read at least ,50 you can also perform the same test with your multimeter on the defrost heater usually around 21 ohms or higher ohms ratios range on heaters as long as it is around 20 it would test good. If both test good then you would look at the defrost timer or adaptive control. When you remove rear panel mentioned and access the evaportator coil any ice build up on the coil has to be defrosted with a hair dryer. if you have any questions message me back. Thank you

How do you check resistance through the heater coil?

To that defrost heater
set the meter to lowest ohms setting
follow wires that connect to heater up to the top of freezer coil
unplug the 2 wires for the defrost heater/or if on huge plug with all wires in unplug that plug
place meter leads on the the 2 wires for the heater
the meter display should be some where between 5-25 ohms of resistiance

if heater is good it will have contunuty with 5-25 ohms,if bad the meter display either wont change or display OL
if heater check good check defrost thermostat pictured below for ZERO ohms resistiance when cold and frost is built up on freezer coil MUST BE COLD to check. It too should have continuty with ZERO ohms resistiance

If both heater nand defrost thermostat check good the defrost control board will be the problem.

This is what the deforst thermostat looks,yours may be slightly different yet very similar and ina similar place(clipped to top of freezer coil usually on right side)

The defrost circuit in you freezer has failed that is why you have to defrost the coils. The defrost circuit consists of the heater element, the defrost thermostat and the control module. The control module turns off the compressor and powers up the heating element to melt the ice on the coil, after the coil reaches 40 deg F the thermostat cuts off power to the heater. The heating element and thermostat is mounted to the coil. If you have a multimeter and know how to use one, you can check the thermostat and heater. You can check the heating element with a multimeter to see if it has electrically opened. If it has then you will need to replace it. Check also the thermostat, it should be in series with the heater. It should read close to 0 ohms if it is freezing and read infinite ohms if the temperature is above 40F. If the thermostat and heater check out, the problem might be with the control module.

GE Profile SxS Refrigerator wont defrost after new heater installed

If one coil was burnt out and you replaced the heaters and defrost terminator switch I would recheck the continuity through the defrost heaters. You can do this with an Ohm meter with the refrigerator unplugged. If you had an open coil in one of the heaters you did not have to replace the thermo disk. If you have a complete circuit through the heaters try using the old thermo disk. If you have a meter you can check the voltage from the heater connection on one side to the inlet side of the thermo disk with the refrigerator running in the defrost mode. You should read 115-125 Volts on the meter. This reading tells you that the defrost timer is supplying power to the heater circuit.

If you are supplying direct current to the heater coil and it is not heating up, then it is likely that the heater coil is faulty and needs to be replaced. The fact that the resistance of the heater coil is 348 ohms suggests that it may be within the expected range for the heater, but this alone does not guarantee that the heater is functioning properly.
Before replacing the heater coil, however, it is important to ensure that there are no other issues with the defrost system. For example, a faulty defrost thermostat or defrost timer can also cause defrost problems in a refrigerator.
It is recommended that you consult with a qualified technician or the manufacturer of your LG refrigerator for assistance in diagnosing and repairing the defrost problem. They will be able to provide more specific guidance on what steps to take next to resolve the issue.
