    Default Ice buildup on freezer vent. Barely cooling enough.

    Model Number: PHT219JKM0
    Brand: Frigidaire
    Age: 1-5 years

    My 18 mos. old Frigidaire has begun to accumulate an ice buildup in the freezer on the right side air vent. At the same time the cooling for both the fridge and freezer dropped considerably. I can still use it by maxing out the temp. adjustment but it doesn't want to make ice, and barely freezes trays. Any suggestions as to troubleshooting or possible solutions would be appreciated. I am not an appliance tech. but am a copier tech. for 25 yrs., so I know circuits, electronics and such.

    I have pulled the rear cover off to clean the coils and verify the fan and compressor are normal. Everything seems to be working....fans and such, just not well enough to cool properly. Thanks.

    So its just frosted in the vent itself? Not the whole back panel inside the freezer?

    Do you hear the fan running inside the freezer?

    Yes, the fan is running. The whole panel is not frosted, just the right vent. I thought initially it might be frosting due to a lack of circulation from too much stuff blocking the vents. I removed all the food, unplugged it and used a hair dryer to melt the ice. It has returned in about 48 hrs. I think the evaporator is behind those vents and suspect the ice buildup may be growing off of that, just not sure if that's possible or why.

    Ok, then remove the back panel from inside the freezer and look at the evaporator coils, normal would be a thin layer of frost on ALL the coils, if its built-up on the right top side then you likely have a sealed system problem that you'd need to get a Frigidaire tech. to come out to fix.

    Check your warranty, some have a 5 yr. warranty on the sealed system/compressor.

    Thanks Jake,
    I finally got around to pulling the panel off and the bottom and right side was frozen solid. (Click image for larger version.

Do you think it's possible the defrost circuit has failed? Or is it definitely a problem with the sealed system? I don't understand why that would have a blockage or failure on this new of an appliance, but I guess they don't build them like they used to. I used my 26 yr. old fridge in the basement to store the frozen stuff removed from this one while I took it apart.

    Yes, thats a sealed system/compressor issue.

    Did you check your warranty?

    I misplaced my owners manual, but downloaded one from the Frigidaire site and it looks like a straight one year warranty. Sucks to have to replace such a new unit, but I guess it's probably not worth sinking a ton of money into.

    Well you have one other way to resolve this that other members have done with good results for free, send an email to the group management of Frigidaire, Electrolux owns Frigidaire. Just explain the problem in a polite way, if you get irate they usually won't help you out.

    Here's the Electrolux group management website to send the email:

    Thanks again Jake. I guess it can't hurt to try contacting the manufacturer. I'll let you know if I have any success.
