FFHB2740PPBA Frigidaire Refrigerator Icemaker not working

Frigidaire

Age

1-5 years

We have a FFHB2740PPBA refrigerator that we purchased in 2017. Two weeks after purchasing, the icemaker stopped working so we called and had a repairman come out, under warranty, to fix it but after two days it still didn't work. I contacted the repairman again and he got hold of Frigidaire, who told him there was a defect with those icemakers and they had issued a solution. Three days later he returned with the corrective part and made the repir.

It has been five years since then and the icemaker worked well until about a month ago when it again stopped making ice. I had the mainboard replaced but no ice; I had the front user display replaced but no ice; and I just two days ago had the and icemaker relaced but no ice. So I found this forum and also a topic about the icemaker not working, so I went into test mode and ran the three suggested test: temperature read at 32F (I dropped the freezer temp to -1F after the test thinking it might need less than 32F freezing in order to make ice), the tray dumps and the tray fills with water. Still no ice.

At this point, I am at a loss as to why the icemaker isn't working, so any advice would be greatly appreciated! I'm thinking we're likely going to need a new refrigerator.

TIA

Your ice maker temperature is too high. It should always be between 0 to 10 degrees for the ice maker to freeze the water into ice properly, and cycle the ice out of the tray on its own.

Do you hear the ice maker fan running behind the ice maker?

I'm attaching the tech. data sheet below.

Look where it says: FRESH FOOD ICE MAKER DIAGNOSTIC MODE

Do TEST 57C and see if the ice maker fan runs.

If the ice maker fan is running, and since its just 32 degrees F in the ice maker compartment, you have a cooling problem in the ice maker compartment. Do you see frost build up behind the ice maker?

You have a defrost thermostat and defrost heater on the ice maker evaporator coil, behind the ice maker. You can ohm test both of those parts. Unplug the refrigerator first before accessing and ohm testing those parts.

Here's the defrost thermostat(limit switch) for your model you can order if yours ohm tests bad:
Defrost Thermostat 5303918810


Watch this video to ohm test it, make sure you unplug the refrigerator before you remove it to ohm test it:

Leave it in the ice water for at least 5 minutes before ohm testing it.

Here's the defrost heater for your model if yours ohm tests bad:
Defrost Heater Assembly 242094802


When you click the part link to the defrost heater you will see videos on how to ohm test the defrost heater and how to access/replace it. The video will also show you how to remove that air handler.

Let us know what you find.

Thanks for responding.

I ran 57C and the fan ran. I have a repair tech coming out on Thursday and I am very interested in what he finds.

I really appreciate your help, especially the .pdf!

Glad to help, let us know what the tech. finds if you could please.

Thanks!

Ok, so the repairman came out and ran his tests that he access by pressing the up and down carrots for 10 seconds. Anyway, he came to the conclusion that the thermistor and the defroster are both bad. He had to order the parts and will be back next week to make the repairs. Hopefully it will all be good.

You mean the defrost thermostat and defrost heater? That I posted in post #2 are both bad?

 

[dreidmiller]

Yeah, that's what he said. He's coming out this coming Thursday so I guess I'll find out if those fix it.

Ok sounds good, yes keep us posted.
