There are three main reasons the fans would not come on.
1: A bad door switch. There are switches on the top part of door frame. They turn fans off when door is opened to prevent warm air from being drawn into unit when door is open. If a switch goes bad the fans will never turn on.
2: Refrigeration problem. The fans are tied into a temperature switch called a fan delay. The fans will not come on until the coil is well below freezing. This is to prevent water spray after a defrost. If unit is low on gas or has any other cooling issue the fans will not come on.
3: Bad fan delay switch. If the fan delay switch becomes "stuck open" the fans will not be energized.

Feel the back of your evaporator coil, if it is very cold and frosted you probably have a bad fan switch, or a bad door switch. ;)

GE bottom freezer stopped cooling


The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions.

The fan on my GT345 chest freezer runs constantly. Is this correct ?


Depends are you referring to the condenser fan or the evaporation fan? If it's the condenser fan you may have an issue with debris in the condenser coil not letting enough air flow to cool down so it will stay on to keep from burning up compressor.If it's inside the evaporator coil then it may be low on refrigerant possibly freezing up the evap coil making it run then kick into defrost run kick into defrost etc... hope this helps

Not freezing


Hello Jim;

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

If you are getting cooling and not freezing your problem is not your overload relay or capacitor, otherwise you would get no cooling at all.

You have one of 4 potential problems.

1.) Frozen Drain - This is a common problem. Your unit goes through a defrost cycle every 8-10 hours, everything shuts down for about 20-30 minutes. This is when your defrost heater turns on and defrost your cooling (evaporator) coil. If your drain is frozen, a wall of ice builds up behind your lower back wall. This prevents the cooling fan from running and air flow through the cooling coils.

You need to remove the lower back cover to see what is going on. there are several screws holding it on. First remove the rubber seals on both sides. They just pull out.

If it is a block of ice, use a hair dryer to melt the ice and clear the drain. Do not try to chip away, you will damage the coils.

2.) If you observe the cooling coil fan not running and vibrating, then you need to replace the fan.

3.) Defrost Heater - You may have a bad defrost heater. Observe, is the glass tube black or is the wire inside broken?

4.) Refrigerant leak or obstruction - If you observe a block of ice in the upper right hand corner of your cooling coil, then you either have a leak or an obstruction. A repair of this nature with a service company is about $500.00.

5.) Bad Bi-Metl (Thermostat) - In the upper right corner is your cooling coil thermostat.

If you observe the flat back has popped open, then replace.

Delay on evap. fan sistm.404a


Give the evaporator a chance to get cold, then check you've got power to the fan, via the evaporator thermistor and door switch

We have a True TS-49F freezer that the interior fan have stopped working. Holding the door switch does not activate them. Unit is out of warranty.


Most all commercial freezers like yours have, what is called, a fan delay. It is located in the evaporator case and is usually attached on or very close to the actual cooling coil. It may also be a combination switch known as a defrost terminator/ fan delay. It's purpose is to keep from circulating warm air. If the cooling coil does not reach a preset temp, the fans do not come one. Another thing is that the fan motor may just be bad. If you have more than one fan, then chances are that it's going to be the fan delay. I would start there to see that either the fan delay switch is bad or there is a reason that the coil is not getting cold enough to activate the switch.
