Changed water filter red light stays on

Green light usually means your water filter is in great condition . the light will stay on,over time change to amber then red. Red means change filter

Thank you for your inquiry, John Sodt!
From what you have described your Frigidaire refrigerator's filter display is not changing back to green after the filter has been changed. This could be a miscommunication within the control panel and to clear out any miscommunications I would suggest performing a reset on your refrigerator. The best way to reset your refrigerator is to unplug the power cord for roughly ten minutes. If that does not help your issue you may want to speak with a professional technician. Good luck. -Matt

Check to be sure your water source is on. Low pressure may make the filter sensor think there is a plugged filter.

HI, if yours is similar to mine with ice maker and gets used several times a day my light comes on about every 6 mo. but i do have three kids so i use a lot of water. depending on use it could last 11 mos. but i would not go past a year if not used as much.

The light stays on, actually. RF265/6/7 models have a blue LED water filter indicator that remains lit in normal mode. After about 5 months [on a 300 gal. filter] the LED indicator will turn pink and then red at about 6 months. Derived from RF266 users manual, hope this helps.

I am not sure but check the owner's manual and see if you have to reset something when the filter is changed.
Good Luck,

Water Filter Status Indicator
Light (select models)
The Water Filter Status Indicator Light serves as a
reminder to replace the water filter. A green light
indicates that the filter is in good condition. A red light
indicates the filter should be changed. Once light turns
red, it will remain red until function is reset.
To Reset Indicator:
• Press and hold both the Lock and Water
buttons simultaneously for four seconds. The
green filter status indicator light will flash
three times when the function has
successfully reset.

The LED monitor should light up as Green when the membrane is producing the proper water quality (80%+ TDS rejection). If the LED light stays Red this indicates the RO membrane is bad, all the filters (including membrane) should be changed and system sanitized. The batteries in the TDS monitor should be changed yearly also. Don't have a lot of faith in that indicator light. The best way to test for TDS rejection is with a digital TDS meter which indicates the amount of rejection. Compare the incoming water to the product water of the RO.
