About this model
Model overview
What we know
The FFPS3133UM is listed as a Frigidaire refrigerator. General behavior is described here, and the rest is checked at the visit.
Display messages
Some messages are simply states, not faults. Sabbath Mode is a setting that limits some functions on purpose, and Demo Mode is a store-display state that leaves components idle. Others are real: a start-up communication failure and a communication error mid-run point to the link between the user interface and the main control. Compare what your screen says with those entries before you do anything else.
If there is a dispenser
A chute jam often appears as a tone and the message DI SP, and our code page describes it as an ice jam in the dispenser chute. Do not use a knife or screwdriver on it. Leave the cabinet to warm gently and keep your fingers out of the chute.
Cold on the wrong side
Lettuce that turns hard and glassy means the fresh-food space is getting too much cold air. Take a look at Frigidaire refrigerator freezing food in the fresh-food section. Before you call, move food away from the back wall and see whether the effect changes.
Checks that are safe
- Close the doors fully and make sure nothing sticks out of a bin.
- Check the water supply valve if a water line is attached.
- Photograph the display message.
- Do one reset and wait.
Booking
The Frigidaire refrigerator repair page lays out the visit; Frigidaire refrigerators shows where this number fits. You get a written estimate, and nothing is repaired without your approval.
Cleaning the dispenser area
Spills in the dispenser tray and around the front can freeze and block the chute. Wipe the area with a damp cloth, dry it and keep the tray clear. Avoid spraying cleaner near the buttons, since moisture behind the panel can cause display trouble that looks like a failure.
Before the technician arrives
Clear a path from the front door to the kitchen, move anything stored on top of the cabinet, and make sure the area around the unit is open. If a water line feeds the cabinet, know where the supply valve is, because we may want to close it. A quiet, uncluttered kitchen makes the diagnosis faster.
Frequently asked questions
Our code page notes that it is not a fault. It is an active setting.
A tone with DI SP means an ice jam in the chute according to our code entry.
It is a store-display state, so a unit installed in a home should not stay in it. We check it on site.
Only after we have shown the fault to be there and you have approved the written estimate.
