Brand:Frigidaire Model Number: Fpru19f8rfc Main Symptom: condensation, door alarm What happens & when: door alarm goes off, reset button only works for a couple minutes. Unplugging and hard resetting only works if left off long enough for temperature to rise enough for unit to kick on or else door alarm starts again. There is usually excessive condensation (puddle on the floor) when this happens. If hard reset works it may work for 3-4 hours or up to 12+ hours
Error Code (if any):
Parts or tests already tried: new door seal

For a Frigidaire Professional FPRU19F8RFC all-refrigerator, the combination of:
Repeated door alarm
Heavy condensation/water on the floor
Alarm temporarily clearing after power resets
Problem returning after a few hours
points more toward a door switch / door sealing / air infiltration issue than a cooling system problem.
Most likely causes (in order)
1. Faulty door switch (highest probability)
The control thinks the door is open even when it is closed.
Symptoms that match:
Door alarm sounds even with the door shut.
Reset only silences it temporarily.
Warm, moist room air continuously enters, creating condensation and puddles.
Unit may operate normally for a period before the alarm returns.
Check:
Press the door switch by hand and see if the interior lights go off immediately.
Wiggle the switch while pressed.
Look for broken mounting tabs or moisture around the switch.
2. Door not sealing properly
A leaking gasket allows humid air into the cabinet.
Symptoms that match:
Excessive condensation.
Water on the floor.
Temperature fluctuations.
Alarm may occur if the door isn’t fully closing.
Check:
Inspect the gasket for tears, gaps, or deformation.
Look for areas where the gasket doesn’t contact the cabinet.
Perform a dollar-bill test around the entire perimeter.
3. Condensation drain issue
If the drain is restricted, water can accumulate and leak onto the floor.
However, a clogged drain alone usually does not cause a door alarm, so this is likely secondary.
4. Main control board misreading the door circuit
If the door switch tests good and the door seals properly, the control board may be intermittently interpreting the switch as open.
The fact that:
Power cycling temporarily resolves the issue
Duration varies from a few hours to half a day
could indicate an electronic control issue.
Questions that would narrow it down
When the alarm is sounding, are the interior lights on or off with the door closed?
Do you see condensation mainly:
Around the top of the door?
On shelves and walls inside?
Or underneath the unit on the floor?
Does the display show any error codes?
The answer about whether the interior lights stay on during the alarm will help determine very quickly whether the door switch circuit is the primary failure.
Interior lights work til the third time alarm goes off then are shut down also. Very little condensation inside the fridge except some on the contents, not much on the fridge components. New door seal already installed to little or no effect. And the condensation is mainly showing itself as a small puddle on the floor.
I tapped it a few times initially and it seemed to be working fine. I did not try juggling or tapping it while in the closed position though. And the hard resetting only seems to work if we wait long enough for the interior temperature to rise enough that the unit kicks on when plugged back in.
