Tip & How-To about Refrigerators

Hot door seal, rail, divider strip between refrigerator and freezer.

If the mullion (rail between the fresh food section and the freezer section) on your refrigerator is hotter than normal this tip will help identify and remedy the issue hopefully before it gets to the point of loosing the cooling.

Theory:
Refrigerated surfaces will attract moisture, especially in the warmer more humid areas and times of year. Since the refrigerator and freezer are cold moisture can accumulate near the door from normal use, this moisture can get into the door seals and cause them to not seal properly, mold and otherwise cause a nuisance.

Why Hot:
To keep the moisture from accumulating on this surface the refrigerator manufactures have run part of the hot condenser tubing inside the cabinet close to that rail, under normal running circumstances this rail will be slightly above room temperature and the amount of heat not noticeable. The condenser is the set of coils that are on the back or bottom of the refrigerator and disperse the heat from the unit. If the condenser is very dirty or the fan that keeps the condenser cool is not running then the condenser coils and thus the mullion (rail) gets very hot and overheats. This heat will eventually cause the compressor to work harder and possibly overheat and turn off occasionally to cool itself. This will lead to reduced cooling in the freezer and refrigerator.

Fix: If the coils are under the refrigerator, pull the front grille off of the bottom, check if you feel air coming out, if not then the fan is not running, look for dust and dirt build up on the coils, clean with a brush and vacuum, do not be afraid to get aggressive with the brush. If the fan is not running you will need to go to the back of the refrigerator and unplug the power cord. Remove the back panel off the bottom and you should see the fan. It may have some dust or other debris blocking the fan blade from turning. If so clean that out very good, clean the coils from the back if accessible also. Be sure to put the back panel on as it is there to direct the air flow across the compressor and coils, without that panel the condenser will overheat.

If the fan does not run after cleaning it you will need to replace the fan motor, it is a common part that should be available at most retail appliance part dealers. Just be sure to get your model and serial number before calling.

We just got our new frig anf freezer is blinkinf h1 what does this mean


Hello;

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

H1 is really HI. Your freezer is too cold. You only have one source of cooling and that is your freezer. You freezer also cools your fresh food section. Your freezer will meet its temper setting before it meets your fresh food section.

The normal setting for the freezer is -2 to + 2 degrees F. and the normal setting for your fresh food section is 35-40 degrees F. Adjust to these settings. Wait 24 hours for your system to stabilize.

If the error code does not go away or your freezer and fresh food section are reasonably within the above settings, then you need to contact the store where you purchased it.

It is not uncommon for a new unit to be delivered one day and I am there the very next.

what should the temp be for freezer and refrigerator?


dont know model, do know temps. The fridges highest temp is 5deg c, preferably between 1 and 4, if freezer goes above minus(-)18deg c your are in danger zone, there should be a regulator control in the fridge, usually on left or right hand side near front(door)

middle frame between doors is very hot on whirlpool


Practically all refrigerators have what is called a "mullion heater" between the freezer and fresh food compartments. Otherwise, the wall separating the fresh food and freezer compartments would freeze as well as the fresh food compartment. Some heaters are a bit warmer than others according to brand of appliance.

Fresh food section not maintaining cold temp


You're frozen up.  Defrost completely.  Then, clean your condenser.  Make sure to never leave open containers in the fridge...water condenses into ice.  If you still have problems, you may be low on gas.
