Inspect the Heater's Settings and Controls

Sometimes, the issue might be a simple user error or improper settings. Ensure that the heater is set to 'High' or 'Low' heat setting and not 'Off'. Check that the thermostat is set to a temperature above the current room temperature. If your heater has a timer function, ensure that it's not set to turn off during the time you're trying to use it.

Additionally, verify that the fan setting is set to 'On' if you want the heater to run continuously, even when the room has reached the desired temperature. If the fan is set to 'Auto', the heater will only run when the room temperature falls below the set threshold.

Check the Internal Fuse and Thermostat

Locate the internal fuse inside your Lasko 5622 heater. Most heaters have a user-accessible fuse for safety purposes. If the fuse is blown, replace it with an identical fuse to resume operation. If the fuse blows repeatedly, there might be a short circuit or other electrical issue in the heater that requires professional repair.

The internal thermostat controls the heater's operation. If it's faulty, the heater might not turn on or might not maintain the desired temperature. To test the thermostat, insert a thin object, such as a paperclip, into the small hole next to the thermostat. If the heater turns on, the thermostat is likely faulty and needs replacement.

If you've agot through this comprehensive guide and haven't found a solution, consider contacting Lasko's customer support or consulting a professional heater repair technician. They can provide personalized assistance and help you resolve your Lasko 5622 heater not turning on issue. Always remember to prioritize safety when working with electrical appliances.
