Carrier Infintity System Fault Code 198, Input G Alert

My Carrier Infinity FE4ANB006 heat pump is terrific for cooling and dehumidifying my Florida home but for the past week, INPUT G ALERT and FAULT CODE 198 are displayed on the control panel. I've contacted the installer, but haven't heard back from them. .

Perhaps this is important: the electrical power was out for one week in my area from Hurricane Irma. These fault codes appeared after the power came back on.

An Internet search did not reveal anything for code 198 or Input G alert.

My system is cooling/dehumidifying satisfactorily.

What do these codes mean? How to address them?

Input G usually means a drain issue.

What thermostat do you have ?
Infinity color touch screen or monochrome Infinity with buttons?

The Infinity thermostats may be able to define code 198.

Thanks for the reply.

My system is the color Infinity touch screen.

Have you tried getting the thermostat to define the problem?

Surf to the service picture of a hat, push and hold it for about 12 seconds and it will turn a yellow green.
Surf to service and then select last 10 system events.

SOLVED.

The Safe-T-Switch float switch (next to the indoor air handler) reservoir had enough water in it to elevate the floating sensor.

I pulled the float switch out of PVC tube holder, dumped out the water, then replaced the Safe-T-Switch.

The error message FAULT CODE 198, INPUT G ALERT message is now gone.

Houston204: I did what you said, holding the "hat" icon and found the system events. That was very interesting. Thank you.

All is normal now. Thank you.

You will need to blow out the drain to prevent another float switch trip.
