What F4 E1 / F4 E2 (110 / Whirlpool-built VMAX) Means
F4 E1 and F4 E2 on the Whirlpool-built VMAX dryer report a heater relay fault on the electronic control board — the switching that decides when heat is applied is no longer behaving as commanded.
Common Causes of F4 E1 / F4 E2 (110 / Whirlpool-built VMAX)
- A heater relay failed on the electronic control board
- Damaged wiring between the board relays and the heat source
- Surge damage affecting the relay drive circuit
🔧 One Safe Check You Can Try
Stop the cycle and switch off at the breaker; anything involving uncommanded heat in a dryer deserves that response before a diagnosis is even attempted.
⚠ Why You Shouldn't Go Further Than That
- A relay that will not open can leave heat applied when the control thinks it is off, which is a genuine fire-safety concern rather than an inconvenience.
- On gas models the gas supply is shut off at the appliance valve before the cabinet is opened, and power is cut on every model.
- The heat circuit carries the full supply, and on electric dryers that is 240 volts rather than household 120.
