Why the control reported this error
The dryer is detecting an invalid incoming power-source frequency because unstable or incompatible power source. generator or inverter frequency outside specification and control detecting abnormal line frequency can produce the same code, so verify the fault before replacing components.

Diagnostic sequence
Work through these checks in order
Stop when you find the fault. Do not perform a step that requires skills or live testing you are not qualified to do.
- 1
Check 1
Stop the cycle and restart the dryer.
- 2
Check 2
Confirm the dryer is connected to the intended household power source.
- 3
Check 3
If operating from a generator or inverter, verify that source meets the dryer specifications.
- 4
Check 4
Request service if the code persists on normal utility power.
Recommended next step
Troubleshoot before buying a part
This code does not point to a replacement part as the first action.
Follow the diagnostic sequence above first. Supply problems, maintenance conditions, settings, airflow restrictions, or temporary control states can often trigger this code without a failed component.
If the code returns after the listed checks, use the complete model number and manufacturer documentation before ordering anything.
Common questions
Quick answers for this fault
What should I check first for FC / FE?
Start with unstable or incompatible power source. If that checks out, continue through the diagnostic sequence above rather than replacing a part based on the code alone.
Do I need to buy a part for FC / FE?
Usually not as the first step. This code is commonly tied to a setting, supply issue, maintenance condition, airflow restriction, or temporary operating state. Complete the diagnostic checks before considering parts.
When should I stop troubleshooting FC / FE myself?
Stop if the next step requires live electrical testing, sealed-system work, gas or combustion service, or any procedure outside your training. Disconnect electrical power before removing panels or handling internal components. Do not bypass safety devices or perform live electrical testing unless you are qualified to do so.
