If the heater is geting hot and not cooling sounds like it is in the defrost mode just defrosting or stuck in defrost mode.If it is in defrost mode it should stop defrosting after a while and start cooling. They defrost every so many hours depending on how they are set.

The outside of my refridgerator is hot and the food is getting hot to. It is a Maytag.


Are you sure it is a refrigerator and not an oven?

The outside generally warms up while the compressor is working - or at least the area where the condenser is. If the cooling circuit isn't working then the outside doesn't get warm and the inside doesn't get cold but if the outside is getting warm it can only be because the inside is getting cold - or at least should be.

I expect the defrost heater which should operate only briefly after each cooling cycle to melt any frost that has formed over the evaporator has, because of a fault, remained switched on causing the oven effect. This will force the compressor to work harder and cause the outside to be warmer than usual.

I suggest you contact the repair shop as soon as possible. The fridge will probably be cooler switched off and loaded with ice from the freezer or frozen cool-packs.

I doubt the internals of your fridge are easily accessible but if they are (safely) disconnecting the defrost heater could effect a temporary solution.

Refrigerator is hot but the freezer is cold


If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked. Frost formation without defrosting could block the air flow and so shut the air passage to the fridge. Also the blower fan must work and if this is not working then the fan can be faulty. Also a fault on the control unit is a suspect to non functioning of any one of these components.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

My refrigerator is not get cold its cool but not cool enough for milk


Hello,

Insufficient cooling is a fridge repair job that you can do without the help of a professional. Often the fridge has a frost-free failure, or the compressor is faulty but there are many other reasons for a fridge not cooling properly.
Step 1 - Find the Problem

Your first job is to locate the source of the problem. Consider each of the following:

* Gaskets - Make sure the gaskets/seals are not torn and are sealing properly.
* Evaporator fan - Make sure it is working. If it is now working you may have a problem with the fan motor. Check for power to the motor and also examine the fan switches around the door (not all fridges have these switches).
* Air damper - Sometimes the air damper will not open up to allow the cold air from the freezer part to blow into the fridge section.
* Condenser coils - Check to see that the condenser coils don't have a dust build-up and that the condenser motor is working.
* Compressor - Make sure your compressor is working with on and off clicking noises.

Step 2 - Frost-Free Failure

This is the most common cooling problem in fridges. Expose the evaporator coils by accessing the panel in the freezer section. The coils in the freezer section can sometimes get clogged up with frost. This can stop the evaporator fan motor from blowing cold air around, or cause the fan to hit it and stop, or become noisy. The defrost timer can be a bit tricky to find but it is usually located behind the back bottom corners of the fridge, although they can sometimes be found in the ceiling of the fresh food section, or behind the cold control cover.
Step 3 - Find the Timer

When you find the timer, turn the wheel-like screw slowly with a screwdriver until the fridge shuts off. The refrigerator is now defrosting. If you find that the fridge starts now, you will need to replace the defrost thermostat and the defrost timer.
Step 4 - Volt Test

If the heaters do not come on, use a volt meter to ohm test the defrost heater or volt test for 120 volts to the heater. You can bypass the defrost thermostat if you haven't got power to the defrost heater to check if the defrost heater will come on. To bypass the thermostat, join the two wires together. Replace the defrost thermostat and the defrost timer if the heater comes on now.

If there is a ticking or squealing noise in the defrost timer, or it seems hot to touch, replace it.

Many fridges have and inline fuse on both sides of the defrost heater. You will need to replace the whole heater if one of those fuses blows. Check these fuses with a volt meter if the defrost heater doesn't work.

A quick check if you have a cooling problem is to inspect the evaporator coils. If there is a build up of white snow on the coils, this indicates a frost free problem; if there is balled ice on part of the coils with the rest bare, this indicates a system problem, like a problem with the pumping compressor.

Hoping this will help in solving the problem......

Camper fridge dont cool


I also had the same Model Make. I removed my fridge and placed it upside down, occasionally shaking fridge within a 24 hr period. This seemed to re-mix the ammonia solution and the fridge is working.
This may work for you but look for yellow stains if you see any your fridge is leaking and would require repair.

I have a Dometic RV fridge that wont get cold. It is a model RM 2401. It easily lights on gas, the coils get hot and it makes a little gurgling noise but does not get cold. Can this be recharged?


It sounds like your cooling unit is going out. Here's a couple of things to check. Do you smell any ammonia when you open either one of the doors? When you look at the rear of the fridge, do you see anything that looks like rusty water that has run down any of the metal tubes and dried up? If the answer to either one of these is "yes", then youll need to start looking for a new fridge or replace the cooling unit on the one that you have.

Not getting cool enough


this sounds like a compressor problem. if the outside coils are getting hot (and properly ventilated) but the inside of the unit is not getting cold then the heat is coming from the compressor.
