Answer to continue safely
Is it safe to keep using?
No. An element circuit fault must be diagnosed before the range is used. A shorted element can trip the breaker unexpectedly during cooking, and a welded relay can cause an element to heat uncontrollably. Neither condition is safe. If the fault is confirmed as a simple open circuit in one element, other elements may function, but this should be confirmed by a technician.
Can I reset the code?
Yes. A power cycle may clear the code temporarily, but E2 will return as soon as the faulty element circuit is engaged. The underlying fault — whether failed element, relay, or wiring — will not resolve itself through resets.
When to stop immediately?
Stop if you notice: If the circuit breaker trips when the range is used, do not reset the breaker repeatedly — a repeating trip indicates an active short circuit that must be repaired., If you see a visible break or burn mark on a heating element, stop using the oven and arrange replacement before next use..
Symptoms You May Notice
Oven does not heat despite appearing to operate
The control panel shows the oven as active and counting up toward the set temperature, but no heat is produced and the cavity remains at ambient temperature.
E2 code displayed on control panel
The fault code appears on the display, often after the oven has attempted to heat and failed to detect the expected current draw from the element.
One or more cooktop elements fail to heat
Individual cooktop elements may not respond to selection, or respond but produce no heat, alongside or independent of the oven fault.
Circuit breaker trips when range is used
The dedicated range breaker trips to OFF when the oven or a cooktop element is activated, indicating a short circuit in the element circuit.
Possible Causes
Failed bake or broil element
The heating element has burned open (no current) or developed a short to ground (causing a breaker trip), with both conditions triggering the E2 circuit fault.
Requires ProfessionalFaulty element relay on control board
The relay that switches power to the heating element has failed open or welded shut, producing an incorrect circuit condition that the board detects as an E2 fault.
Requires ProfessionalDamaged element wiring or connections
Wiring from the control board to the heating element has an open circuit or short, preventing proper current flow through the element circuit.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the range
Turn off the circuit breaker for two minutes and restore power. Attempt to preheat the oven to a moderate temperature and observe whether E2 returns immediately or only after several minutes.
An E2 that appears immediately at the start of heating usually indicates an open element (no current). One that appears after several minutes often points to an intermittent connection.
-
2
Visually inspect the bake element
With the oven cooled and power off, remove the oven racks and visually inspect the bake element at the oven floor (or hidden bake element cover, if equipped). Look for a visible break, blister, or burnt spot on the element surface.
A failed bake element often has a visible crack or hole where the wire burned through. This is one of the few electric range faults that is visually confirmable.

3
Check if the breaker has tripped
If E2 appeared alongside a tripped breaker, reset the breaker once and attempt to use only the cooktop elements (not the oven) to determine whether the short is isolated to the oven circuit.
If the breaker trips again on cooktop use, the fault is in the cooktop wiring or an element — not the oven circuit.
When to Call a Professional
Contact a qualified technician if:
- Element testing requires measuring resistance across the element terminals with a multimeter — an open circuit reads infinite ohms; a healthy element typically reads 20–50 ohms depending on the model.
- Relay testing on the control board requires safe access to live circuit measurements — not appropriate for unqualified personnel on a 240V appliance.
- Wiring replacement inside the oven cavity requires heat-rated materials and correct routing to pass through the range's insulation without creating new fault points.
