The question is why would you want to and which limit are you suggesting? Bypassing any limit would decrease the safety features designed to protect the equipment and occupancy. Limits and safety interlocks are sometimes bypassed for troubleshooting purposes or emergencies but I would not unless you have qualifications to determine the consequences.

What is the process for furnace limit switch replacement?
To replace a furnace limit switch, first turn off the power to the furnace. Locate the limit switch, typically near the heat exchanger. Remove the old switch by disconnecting the wires and unscrewing it from the mounting bracket. Install the new switch by attaching the wires and securing it in place. Turn the power back on and test the furnace to ensure the new limit switch is functioning properly.
How can I test the limit switch on a furnace?
To test the limit switch on a furnace, you can use a multimeter to check for continuity. First, turn off the power to the furnace. Then, remove the wires connected to the limit switch and set your multimeter to the continuity setting. Touch the probes to the terminals on the limit switch. If the multimeter beeps or shows a reading of zero ohms, the limit switch is functioning properly. If there is no continuity, the limit switch may need to be replaced.
What is the function and importance of a furnace limit switch in a heating system?
The furnace limit switch is a safety device that monitors the temperature inside the furnace. It is important because it helps prevent the furnace from overheating, which can lead to damage or even a fire. When the temperature reaches a certain level, the limit switch shuts off the furnace to protect it and the surrounding area.
How can I test a furnace limit switch to ensure it is functioning properly?
To test a furnace limit switch, you can use a multimeter to check for continuity. First, turn off the power to the furnace. Then, remove the limit switch and test for continuity between the terminals using the multimeter. If there is no continuity, the switch may be faulty and needs to be replaced.
How do you repair a furnace limit switch?
