I have a frigidaire gallery model plhs267Za side by side fridge, I came home today and everything in the freezer has defrosted, it is making a strange buzzing sound on and off.. can anyone help? thank you

I would look under the fridge for a drip pan that might be full, so when it defrost it overflows the pan and runs on the floor. If not that you must have a blockage somewhere in the drain line that runs to the drip pan. Take out the shelves and take off the plastic panels to access the drain and drain line, pour some warm water down the drain to unplug it.

Change out the defrost control and cold/temp controls.
See a similar schematic at:

As insignificant as it may seem, that evap fan motor is as important as petrol in a car. That fan controls the fridge cooling on many fridges and circulation in tha freezer compartment. Replace it with the correct one and you should see a functional fridge/ freezer again. Note, i wouldnt run unit without it for long, as condensig temperatures run high and compressors dont last long.

How to check everything

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.


If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

This is a drawback of most mini-fridges. Start by defrosting everything. Then fill ice cube trays with water and keep lowering the setting until the water freezes. Just go a little lower, no more. Fridge should not freeze food. If the fridge stays closed all the time food will freeze. Also if the freezer element gets ice buildup it must be defrosted. Not automatic like home fridge. Most kids today weren't born when the last fridges that had to be defrosted were in service.

you may have a big problem not sopose have the door open so long better you call service

The guide that funnels the water into the ice maker needs to be replaced. The cause of your problem is that water is leaking into the back, freezing there, and blocking the air flow. Mine sounded like an idling semi truck with engine problems.

drip tray usually located at bottom of fridge at rear.sounds like defrost timer is no good,some models can be manually manipulated its located at bottom front panel or at back of fridge,if this is the case defrosting the fridge results in operation o.k. for a short period then gradually dying again

It sure sounds like a compressor problem to me. The buzzing sound is the compressor trying to start followed by a click which would be the overload protector tripping.

You have a bad diode on the water valve connection frigidaire has a kit for this fix..
