How to get rid of control lock on GE microwave?
To turn off Control Lock on your GE JVM3670BF06 microwave/hood combo, press and hold CLEAR/OFF for about 3 seconds until “CONTROL LOCKED” or “LOCKED” disappears from the display (the same step locks and unlocks the controls). See the owner's manual for the exact keypad layout on your unit.
Quick steps to unlock the controls
- Make sure the microwave is not running.
- Press CLEAR/OFF.
- Keep holding for about 3 seconds.
- Watch for “LOCKED” or “CONTROL LOCKED” to turn off.
- Try a simple function (like Add 30 Sec) to confirm the keypad responds.
If it still shows “LOCKED”
- Press and hold CLEAR/OFF again for a full 3 seconds (a short tap usually just clears the display).
- Close the door firmly; the door must latch fully for normal operation.
- Unplug the microwave for 30 seconds, then plug it back in and retry the unlock step.
What you should see
| Display message | What it means | What to do |
|---|---|---|
| LOCKED / CONTROL LOCKED | Keypad is locked (child lock-out) | Hold CLEAR/OFF ~3 seconds |
| No message, keypad works | Controls are unlocked | Use normally |
Why it matters
Control Lock (child lock-out) prevents accidental starts and unwanted keypad changes, especially in a busy kitchen. Unlocking restores normal use of cooking modes, vent fan, and cooktop light.

How to reset GE microwave after power outage?
After a power outage, we reset the GE JVM3670BF06 microwave/hood combo by unplugging it (or switching the breaker off) for about 1 minute, then restoring power. If the display shows LOCKED/CONTROL LOCKED, press and hold CLEAR/OFF for about 3 seconds to unlock.
Quick reset steps (JVM3670BF06)
- Turn the microwave off and unplug it; if it is hardwired, switch the circuit breaker off.
- Wait 60 seconds.
- Restore power.
- If the oven will not start, open and close the door securely.
- If LOCKED/CONTROL LOCKED appears, press and hold CLEAR/OFF for about 3 seconds.
- Reset the clock and any saved settings.
If it still will not start
A power outage can trip a breaker, blow a house fuse, or leave the control in a confused state. Work through these checks in order:
- Confirm the outlet has power (try a small lamp or phone charger).
- Check your home breaker or fuse and reset/replace if needed.
- Make sure the 3-prong plug is fully inserted.
- Close the door firmly; the microwave will not run if the door is not fully latched.
- If the unit runs but does not heat, follow the troubleshooting path in owner's manual.
What the symptoms usually mean
| What you see | Most common cause | What to do |
|---|---|---|
| Blank display after outage | No power to outlet or tripped breaker | Restore power, then do the 60-second reset |
| Display on but buttons do not respond | Control lock enabled | Hold CLEAR/OFF about 3 seconds |
| “Oven will not start” | Door not closed or power interruption | Re-seat plug, open/close door, reset power |
Why it matters
A full power reset clears minor control glitches caused by a surge and gets the door interlock and control board back into a normal startup state.

Can a 20 litre microwave fit a dinner plate?
A “20 liter” capacity alone does not guarantee dinner-plate fit. What matters is the GE JVM3670BF06 cavity width and the turntable diameter; most standard 10-inch dinner plates fit in over-the-range microwaves, but plates with wide rims can rub the walls or stop the turntable. Check the size guidance in the owner's manual.
Quick fit check (no tools)
- Measure your plate across the widest point (rim to rim).
- Place the plate centered on the turntable.
- Close the door fully; the door must latch securely for operation.
- Spin the turntable by hand one full rotation; it should clear the side walls.
- If it drags, try a smaller plate or a plate with a narrower rim.
What “20 liter” does and does not tell you
“Liters” describes overall cavity volume, not the usable diameter on the turntable. Two microwaves can both be 20 L but have different turntable sizes and interior shapes.
Typical plate sizes that usually work
| Plate type | Typical diameter | Fit likelihood in most OTR microwaves |
|---|---|---|
| Salad/dessert plate | 7 to 9 in. | Very likely |
| Standard dinner plate | ~10 in. | Likely |
| Large dinner/charger plate | 11 to 12+ in. | Often too large |
Why it matters
If a plate contacts the cavity wall or stalls the turntable, heating becomes uneven and you can get noise, vibration, or poor cooking results. Keeping food centered on the turntable helps it microwave more evenly.
Related safe-use tip
Use microwave-safe dinnerware (no metallic trim or metallic-looking glaze). The manual includes a simple test using a dish and a measuring cup of water.

What does PF stand for on a microwave?
PF on a microwave display stands for power failure. On your GE JVM3670BF06 microwave/hood combo, it typically appears after a brief outage or power interruption; clearing it usually just requires resetting the clock (see the JVM3670BF06 owner's manual).
What to do when you see PF
- Press Clear/Off to stop any beeping and exit the message.
- Reset the clock and re-enter any preferred settings.
- If the display shows 888 or 8888, treat it the same way; it is another common post-outage display.
- Confirm the microwave is plugged into a properly grounded 3-prong outlet.
- Avoid using an extension cord; use a dedicated outlet/circuit as outlined in the JVM3670BF06 installation guide.
Quick checks if PF keeps coming back
Repeated PF messages usually point to an unstable power supply to the microwave.
| What you notice | Most likely cause | What we recommend |
|---|---|---|
| PF after storms or neighborhood outage | Utility interruption | Reset clock; normal operation |
| PF when another appliance starts | Shared circuit or voltage drop | Move other loads off the circuit |
| PF when opening/closing the door | Loose plug or outlet issue | Reseat plug; check outlet fit |
| PF randomly during cooking | Intermittent power connection | Have the outlet and circuit checked |
Why it matters
A microwave that loses power can stop mid-cycle and may not vent properly during cooking. For over-the-range models like the GE JVM3670BF06, a stable, grounded power connection also helps protect the control board and keeps the hood fan and cooktop light operating normally.

What's the average lifespan of a GE microwave?
Most GE microwaves, including over-the-range models like the GE JVM3670BF06 microwave/hood combo, typically last about 7 to 10 years with normal household use and basic care. Heavy daily use, poor ventilation, and repeated door slamming can shorten that lifespan.
Typical lifespan and what affects it
A microwave’s life is usually limited by wear on the door interlock system, control components, and the high-voltage heating circuit.
- Usage frequency: multiple cook cycles per day wears components faster
- Heat and grease exposure: common in microwave/hood combos over a range
- Door wear: repeated hard closing stresses interlock switches and levers
- Power quality: surges and nuisance trips can stress electronics
- Cleaning habits: grease buildup can restrict airflow and raise internal temps
Quick “repair vs. replace” guide
If your JVM3670BF06 is near the 7 to 10 year mark, use this as a practical decision check.
| Symptom | Common area involved | Usually worth repairing? |
|---|---|---|
| Runs but does not heat | High-voltage circuit (diode, magnetron) | Sometimes (depends on part cost and age) |
| Dead, no display | Fuse, wiring, control | Often (if simple electrical issue) |
| Won’t start unless door is held | Door interlock switches/lever | Often |
| Loud humming or burning smell | High-voltage parts or motor | Sometimes (stop using until checked) |
Model-specific parts that commonly relate to “end of life” symptoms
On GE over-the-range units, door and heating complaints are two of the most common. These parts are listed for JVM3670BF06 and are often involved in those failures:
- Door won’t start or acts intermittent: micro-switch WB24X830
- Door latch feel is loose or inconsistent: microwave door interlock switch lever WB06X10128
- Runs but does not heat (one possible cause): microwave high-voltage diode WB27X1160
- Turntable not rotating: microwave turntable motor WB26X10038
Why it matters
Knowing the typical 7 to 10 year lifespan helps you decide whether a no-heat or no-start problem is a smart repair on your JVM3670BF06, or whether you are likely to see additional age-related failures soon.
For care, cleaning, and troubleshooting steps that help extend service life, use the owner's manual.
