Lennox 8 series ms8-z0-2ap3a error code H1, defrost operation

The manual says this is a normal defrost operation, but the system has been down for almost 3 hours. How do we reset? Is further action needed?

    Should have said this is a mini split system. ZO, not z0.

Code H1 on my frigidaire ffhs2622mwla refrigerator


HI is an error for freezer temperature detected as too warm... Look for frost on the back wall of freezer (defrost failure), or a failed evaporator fan (you should hear it running in the freezer compartment), if the food in the freezer is beginning to thaw, check the compressor to see if it is running. If the compressor is running, but the freezer isn't cold enough, and the evap fan is good with no frost build-up, you may have a sealed system leak (refrigerant charge is low). Frigidaires really suck in recent years and have lots of leak issues...

What does H1 code indicate?


Hello E, I appreciate your post!
I see that your Frigidaire air conditioner is displaying an error code of "H1". I have reviewed the air conditioner and the "H1" error code could be an "HI". The "HI" error code means that the room temperature is above the display range. I would recommend performing a reset on your air conditioner. In order to reset the air conditioner you need to unplug the power cord you can press the reset button and then the test button that should restart your air conditioner. If that does correct your issue I would recommend seeking assistance from a professional technician for proper diagnosis and repair. I hope this information is helpful for you. -Matt

On the refer side we are getting a temp. reading of 67 degrees at the top as you go down it gets cooler to were in the crispers it is 33 degrees, have changed the thermistor and the evap fan motor what...


It could be a problem with the air damper but.... I doubt it.

Down load this manual and go to page 29 of the pdf file,
http://www.servicematters.com/maytag_library/docs/SAM0074.pdf

You will see this:

Self-Diagnostics in the normal operation

2-1) To select this function, press Power Freeze and Power Cool buttons simultaneously for 8 seconds with an audible

tone.

2-2) In the self diagnostic mode, only corresponding LED segments will be illuminated (see the check list on the next

page)
2-3) After a 30 second illumination of error signal, the system will return to the normal operation.

Note the position of the LED in the temp windows and the side that it appears on. Then see the Control panel LED legend along with the corresponding position legend listed below listed on page 30 for interpetation. This should tell you what has failed.
Make sure to read the Details of each failure on page 30 also.

This is the legend.

NO Error

01 ICE MAKER SENSOR

02 REFRIGERATOR SENSOR

03 REFRIGERATOR DEFROST SENSOR

04 REFRIGERATOR FAN ERROR

05 ICE MAKER function error

06 CoolSelect ZoneTM SENSOR

07 REFRIGERATOR DEFROST ERROR

08 EXIT-SENSOR

09 FREEZER SENSOR

10 FREEZER DEFROST ERROR

I have some information on your model and that would involve forced defrost by the service manual page 28 at bottom. How old is your Samsung? Forced Operation Function (Pull-down / Refrigerator Defrost / Refrigerator . Freezer-Defrost / Cancellation)
● This function enables a pull-down mode, a defrost mode for the refrigerator only, a defrost mode for the freezer and the
refrigerator at the same time, and a cancellation of this function.
● Press Power Freeze and Fridge Temp. buttons for 8 seconds simultaneously to get in the ready mode for a forced
operation.
● The display panel will return to normal after 20 seconds in the ready mode.
● At the ready mode, press any button(except Ice Type and Child Lock) once to start a pull-down operation, twice for a
defrost cycle for the refrigerator, three times for a defrost cycle for the freezer and the refrigerator, and finally four times
for cancellation of this function.
● Another way to cancel this function is to simply plug out and in the power cord.
1) Pull-down
1-1) At the ready mode, press any button once then the buzzer will beep (ON for 1/2 second and OFF for 1/2 second)
until this mode is cancelled.
1-2) At this pull-down mode, the compressor will start immediately (No 5 minute delay) and if the system is in the
defrost cycle, it will be cancelled right away.
note) If this pull-down mode begins right after the compressor was off, the compressor may not start to run due to an
overload condition.
1-3) At this mode, the compressor and freezer fan will operate continuously for 24 hours and the refrigerator fan will be
on and off according to the set temperature(34℉)
1-4) After 24 hour operation, the system will be cycled at -14℉ for the freezer and 34℉ for the refrigerator.
1-5) In order to cancel this mode at any time, select the next mode on the ready mode or power off the system.
2) Refrigerator Defrost / Refrigerator . Freezer-Defrost operation
2-1) At the pull-down mode, press any button again on the ready mode to begin the defrost cycle for the refrigerator.
2-2) The beep sound continues for 3 second at the beginning, then ON for 3/4 seconds and OFF for 1/4 second until
this mode cease.
2-3) After this operation, the system will come back to normal operation.
2-4) At this mode, press any button again on the ready mode to operate the defrost cycles for both compartments.
2-5) The beep sound continues for 3 seconds at that time, then ON for 1/4 second and OFF for 3/4 seconds until the
defrost operation cease.
3) Cancellation
3-1) At the R,F-Defrost mode, press ant button again on the ready mode to return to a normal operation.
3-2) Simply unplug the power cord, then plug it again to return to a normal operation.
Press both button for 8seconds at the same time Send maual in one moment, Thanks, Sea Breeze
