Electrolux Dryer Error Code EH1

EH1 on an Electrolux dryer means the control board has detected that the incoming power supply frequency is outside the acceptable operating range. This can be caused by a problem with the household power supply, an incorrect MCF configuration on the control board, or a failure of the main control board itself. The dryer will not operate normally until the frequency issue is identified and corrected.

A reset may temporarily clear the EH1 code, but if the underlying cause is still present, the error will return. If the fault is due to a temporary power disturbance, unplugging the dryer for a few minutes and restoring power may resolve it. If the issue is a faulty main board or incorrect MCF, a reset alone will not fix the problem.

Repair costs vary depending on the root cause. If the issue is simply an unstable power source, there may be no parts cost at all. If the main control board needs replacement, parts and labor typically range from around 150 to 400 dollars depending on the specific board and local labor rates. Getting a diagnostic visit from a technician before ordering parts is advisable.

Some causes of EH1 can be addressed without professional help. Start by checking whether the dryer is connected to stable utility power and not a generator or power strip. If the power supply tests normal at 60 Hz and the fault persists, the repair moves into control board diagnostics or MCF reprogramming, which typically requires a qualified appliance technician.

No, you should not attempt to run the dryer while EH1 is active. The code indicates the dryer is detecting an abnormal electrical condition, and operating it under those circumstances could stress or damage the motor and control electronics. Resolve the power supply or control board issue before resuming use.
