Baxter OV500 Oven Error Code LOC OUT: Control Locked Out
LOC OUT on a Baxter OV500 rack oven with the electronic control means the control has locked out because the oven temperature fell below 150 F. A short beep and then a longer one sound. Note the temperature, check the gas supply valve on a gas oven, let the oven heat back up, and call us if LOC OUT stays or returns.
Low: a protective lockout that often releases when the oven heats back up.

What does Baxter LOC OUT mean?
The OV500 electronic control protects the oven's settings and heating sequence when the chamber has cooled too far. When the temperature falls below 150 F, it locks out and shows LOC OUT. A single short beep and then a longer beep sound, and the control will not accept normal changes while the lockout holds. The message points at a protective state rather than a failed part. It often shows up after a long shutdown, such as overnight, or after a heating problem that let the chamber cool. The manual lists an oven that cooled below 150 F and tripped the lockout, a burner or element that is slow to bring the oven back up, a temperature probe reading that is off or unstable, and a control setting that holds the lockout in place. The first is ordinary and may clear once the oven heats; the others are why a lockout that returns deserves a look. Watching the temperature as it recovers will tell you which situation you are in.
Affected models and control systems
This applies to Baxter OV500 rack ovens with the electronic control. Other Baxter control generations, such as the OV520 Smart Touch, use different messages.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- LOC OUT shows and the control ignores normal changes
- A short beep followed by a longer beep
- The chamber is cool after an overnight shutdown
- The oven is slow to climb back toward the set temperature
Possible causes
Listed in Baxter's documentation
- An oven that cooled below 150 F and tripped the lockout
- A burner or element that is slow to bring the oven back up
- A temperature probe reading that is off or unstable
- A control setting that holds the lockout in place
Other likely causes — what usually sits behind LOC OUT on this control. A technician confirms which one it is before any part is replaced.
- A long overnight shutdown that let a cold bakery chamber fall under 150 F
- A gas oven whose supply valve was closed over the weekend and left the burner unable to relight
- A temperature probe whose reading wanders so the oven seems to cool when it has not
Safe checks before calling for service
- Note the oven temperature and whether the oven lost heat during the day.
- For a gas oven, check that the gas supply valve is open, and never light or adjust gas parts yourself.
- Let the oven heat back up and see whether the control releases.
- Do not keep pressing keys to force a change.
- If LOC OUT stays or returns, call us with the temperature you saw.
How a technician diagnoses LOC OUT
- Read the display and note the chamber temperature and the beeps.
- Check whether the burner or elements call for heat when the oven is cold.
- Measure the heat-up rate against the expected rate.
- Check the temperature probe reading against a reference.
- Review the control settings that hold the lockout.
- Correct the confirmed cause and verify the control releases at temperature.
- A slow heat-up can mean a burner or element problem that needs measuring.
- Probe and setting checks need a meter.
- Gas parts are only for a gas-trained technician.
How LOC OUT differs from similar codes
SHdn on the same control is a safety shutdown that stops heating, while LOC OUT is a lockout after the oven cooled.

Is LOC OUT a broken control?
No, it is the control protecting a setting after the chamber cooled below 150 F.
Will it release by itself?
Often, once the oven heats back up.
What if it returns every morning?
Then the heat-up, the probe or a setting needs checking.
