Your Vornado Heater has a multilevel safety shut-off system designed to prevent overheating. Overheating may occur when the inlets or outlet are blocked. If this happens, the safety shut-off system cuts power to the heater and you must manually reset the heater.
If the air flow through the heater is not adequate, the heater may shut off. Some small heaters have a microtemp fuse that can blow out if the heater is over heated. If that happens, the fuse must be replaced. If the heater is allowed to cool, and it starts up again, there is something that is causing it to overheat.
If room temperature reaches 3 degrees above set temperature, the heat element and fan shut off to avoid blowing cold air.
(WJW) – Thousands of Vornado space heaters sold on Amazon have been recalled amid concerns over possible “electric shock and fire hazards,” according to the company. The issue with the recalled units, marketed as V2 Whole Room Heaters, concerns the power cords, per a recall notice issued last week.

Space Heater Safety Tips
Make sure to keep flammable materials at least 3 feet away. Always plug space heaters directly into a wall outlet and never into a power strip, to prevent overloading and causing a fire. Do not leave space heaters running unattended, including at night when you are sleeping.
If your furnace shuts off after a few minutes and starts more than eight times an hour, it may require repair. Common causes of furnace short cycling include restricted airflow, a malfunctioning flame sensor, or a poorly placed thermostat.
Filthy Air Filter
When this takes place, a safety device switches off the furnace to stop getting too hot. Inspect the filter, and if it's dirty, replace it. From here on out, change the filter every 30 to 90 days to prevent your furnace from short cycling.
Your heater's flame sensor can become corroded over time with contaminants found in the natural gas or propane that fuels your furnace. If the flame sensor is dirty, the furnace will shut off prematurely. To prevent the corrosion from building up, it's wise to have your heater maintained every fall.
A furnace cycling on and off repeatedly can be caused by various reasons, from dirty filters and obstructions in ducts and registers to incorrect thermostat settings and faulty limit switches. By following the steps above, you can help prevent your furnace from cycling too frequently and save energy costs.
Vornado recalled about 7,780 heaters due to a power cord issue that can pose electric shock and fire hazards.
A: The Vornado 630 uses about the same amount of energy as a 50 watt light bulb.
If the pressure drops too low, the boiler may shut down as a safety measure. Thermostat Issues:A faulty or incorrectly calibrated thermostat can lead to the boiler turning off unexpectedly. Overheating:If the boiler overheats due to a blockage or malfunction, it may shut down to prevent damage.
Blockages in the Flue Pipe
Once the gas starts to build up, this may cause your heater to overheat and turn off early. If your furnace keeps shutting off after a couple of minutes, it may be necessary to work with a licensed professional to remove the blockages in your flue pipe and HVAC system.
H.T Leads: H.T leads connect the electrodes and transformers. If these are loose or damaged, this can cause the heater to work sporadically, which is responsible for frequent operation cut outs. Any internal element may be the silent saboteur which is preventing your heater from fully functioning.
Automatic safety shut-off: If your heater keeps going on and off, it could be due to the heater's built-in safety feature. This happens when the heater gets too hot or detects a potential hazard, such as a blockage in the airflow.
This is commonly caused by a dirty air filter. Once high temperatures are reached within the equipment, the limit switch shuts down the heating cycle for safety reasons. Then the furnace must cool down before another cycle starts – but the issue just happens again.
Insufficient airflow or insufficient gas pressure. A defective, malfunctioning ignition board, flame sensor, light switch, thermostat, thermocouple, fan limiter, or draft inducer fan. The drainage line is blocked, resulting in a full condensate pan. Temperatures are so low that the furnace cannot stay lit.
The most common problems that cause a furnace to short cycle include: An overheating heat exchanger. A dirty flame sensor rod. A blocked flue pipe.
A clogged air filter is one of the most common reasons for a furnace shutting off unexpectedly. While it might sound like a minor issue, clogged air filters can significantly impact your system's performance.
The high limit switch consists of a long temperature-sensing probe attached to a metal mounting plate. From the mounting plate, the switch is wired to the blower fan motor and to the gas valve. The switch is generally located just past the heat exchanger. This is so that it can detect the temperature of the supply air.
The heater can overheat and cause the units to melt, catch fire and ignite nearby items, posing a fire and burn hazard to consumers.
Running a space heater overnight increases the risk of fire. If the unit is left unattended or placed too close to flammable materials, such as curtains or bedding, it can ignite and lead to a devastating fire.
- Do not use this heater in an RV, boat or during any application where battery power is converted to AC power. - Place this product at least 3 feet away on all sides from electrical outlets, furniture, pillows, bedding, papers, clothes, curtains and other objects that may cause or catch on fire.
