Jenn-Air Ice Maker LP Error: Low Pressure
What Does Jenn-Air Ice Maker Error Code LP Mean? Error code LP on a Jenn-Air ice maker indicates low refrigerant system pressure. This is a serious issue that points to a refrigerant leak or a restriction in the sealed cooling system. Common Causes Refrigerant leaks develop at joints, connections, and areas of vibration stress over […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Low refrigerant prevents proper ice production and running the compressor with low charge can cause permanent damage.
Can I reset the code?
No. Low pressure from a leak or restriction cannot be reset — it requires professional sealed-system repair.
When to stop immediately?
Stop if you notice: Ice production has stopped entirely, Oily residue visible near connections.
Symptoms You May Notice
Ice production slows dramatically
The ice maker produces far fewer cubes per cycle or the cubes are thin and malformed.
Evaporator coils are barely cold
The cooling coils that should be very cold feel only slightly cool.
Compressor runs but cooling is minimal
The compressor operates normally but the unit cannot reach the required temperature.
Possible Causes
Refrigerant leak
A leak in the sealed refrigerant system has allowed the charge to escape, reducing cooling capacity.
Requires ProfessionalRestriction in refrigerant line
A blockage in the capillary tube or filter drier restricts refrigerant flow.
Requires ProfessionalSafe Checks You Can Do
-
1
Look for oily residue
Check around refrigerant lines and connections for oily spots — refrigerant oil leaks with the refrigerant.
Oily residue near a connection or joint is a strong indicator of a leak.

Note the cooling behavior
Feel the evaporator area — it should be very cold. If barely cool, the system has likely lost charge.
Low pressure issues almost always require professional sealed-system repair.
When to Call a Professional
Contact a qualified technician if:
- System pressure below operating range
- Oily residue at connections indicates leak
- Filter drier is restricted
