We just installed our new GE Elite over the range microwave last week. I tried the sensor reheat for the first time yesterday. I got an F4 error, and figured that it was because my portion size was larger than a single serving. Today, I tried to use the beverage feature (which is also sensor reheat/cooking) to reheat my coffee, and got the F4 error again. The manual doesn't seem to answer what F4 means. Does anyone know? I'm getting the feeling there is something wrong with my brand new microwave....
GE
Microwave Fault Codes
Failure
Code
Condition
Check/Repair
F1
Open sensor, will
occur below 190F of cavity temperature within 15 minutes after
starting convection, combination or roast cook
Check oven temperature
sensor for continuity. Replace if zero or infinite ohms
F2
Shorted thermal
sensor, will occur if a shorted thermal sensor is detected
continuously over 5 seconds on convection, combination or
roast cooking
Check oven temperature
sensor for continuity. Replace if zero or infinite ohms
Note: It will take a minimum of 5 minutes of convection run
time before F1 or F2 code will be displayed if the thermal
sensor is shorted or open.
F3
Shorted key panel
(touch pad), will occur if a shorted key panel is detected
continuously over 60 seconds
Replace key panel
(touch pad)
F4
Open humidity
sensor, will occur if humidity sensor is detected as being
open continuously over 5 seconds
Replace humidity
sensor
F5
Shorted humidity
sensor, will occur if humidity sensor is detected as being
shorted continuously over 5 seconds
Replace humidity
sensor
F6
Shorted temperature
probe, will occur if temperature probe is detected as shorted
continuously over 5 seconds
Replace temperature
probe
ProbEe
Open temperature
probe, will occur if temperature probe is detected open, or
not plugged into the receptacle
If probe is plugged
in and "ProbE" is on display check continuity of the probe
with an ohm meter. If zero or infinite ohms, replace it
F4 means an open humidity sensor, but sometimes this error is bogus and can be reset by unplugging the oven for a minute or so.

Usually answered in minutes!
What does "open humidity sensor" mean, and how do I fix it?
I tried unplugging the microwave for about a minute (probably under a minute, I was impatient), and it didn't help. Perhaps it needs to be unplugged a bit longer.
We paid extra for the model with the sensor heating feature, and we can't even use it! My husband is not going to want to uninstall the microwave and return it, nor is it fair that we would have to pay to repair it ourselves to avoid the hassle.
How does the document you sent for keypad replacement refer to my problem?
Thanks for your help.
