How to adjust the oil heater correctly
1. What is the adjustment method of the oil heater? When using the oil heater for the first time, its thermostat should be adjusted to the middle position to avoid problems. When the oil heater is heated for a period of time, the heating function will be automatically disconnected.
2. During the normal operation of the oil heater, the thermostat should not be set to the highest position for a long time. If the oil heater is in a high temperature state for a long time, it is easy to burn the internal components.
3. How to debug the oil heater? The shift switch of the oil heater can be adjusted according to the indoor temperature. When using the oil heater, pay attention to the airtightness of the room. Because the oil heater is heated by air convection, the indoor temperature will affect the on-off of the thermostat to the power supply.
How to troubleshoot common faults of oil-filled electric heaters
One, no heat
1 , If the power indicator light is off, the heat sink is not hot. First, check whether the voltage of the power socket is normal, and whether there is a broken wire or poor contact in the power plug of the electric heater. Then remove the cover of the power junction box, and first use a multimeter to check whether the over-temperature fuse has blown. If there is still a fault after replacing the fuse, you can measure whether the power transfer switch and the temperature control switch are disconnected or open;
2. If everything is normal and no fault, you can turn the thermostat clockwise to adjust High temperature limit temperature; if the power-on test fault still exists, it may be that there is a poor contact inside the thermostat. Generally, the normal resistance value of the thermostat is zero. If the resistance value is very large during the measurement, the thermostat can be disassembled and the electrical contacts can be finely polished with water sandpaper, and the gap between the contact pieces can be adjusted appropriately. Once the electrical contacts are severely ablated and deformed, they should be replaced.
3. When the fault of the transfer switch and thermostat is eliminated, there may be a problem with the heating PTC. First, check whether the PTC lead wire connector is loose or broken. If there is no above problem, use The multimeter measures the resistance value between the PTC lead-out lines to determine whether the PTC is blown or broken down. When the resistance value of the PTC is measured with the resistance gear to be infinite, it proves that the PTC is damaged. Of course, once the PTC is damaged, it is also very troublesome to replace, because the PTC is sealed in the heat sink, and it is very difficult to disassemble without special equipment tools.
Second, the temperature regulation is out of control
1. What is the maintenance method for the fault of the oil-filled electric heater? After the electric heating oil heater is powered on, the indicator light is normal, and the heat sink is normally heated. However, when adjusting the temperature control, it may be caused by the breaking and falling off of the limit pin of the thermostat. At this time, a new thermostat should be replaced.
2. During inspection, it is important to observe whether the hot metal sheet of the automatic control device is ablated and oxidized, whether the position of the pressure plate is deviated, and whether the size of the contact gap is appropriate. When ablation and oxidation occur between the contacts, after fine grinding and smoothing the contact surfaces with water sandpaper, readjust the distance between the two contacts. The adjustment of the contacts is relatively simple, as long as the two contacts are closed when they are released, the needle-nose pliers should be used to correct the deviation if there is any deviation.
Three, the heat sink is electrified
1. The heat sink of the electric oil heater is generally not electrified. If electrification occurs, it is mostly induced electricity or power leakage. caused by. If there is a slight electric numbness when touching the heat sink, it is likely to be caused by induction electricity, even if the environment used is humid, and the electric heating oil is infiltrated by moisture. At this time, the use environment needs to be replaced.
2. If the degree of electric numbness is serious, it may be caused by power leakage. At this time, check whether the connecting wires in the power junction box collide with the shell and whether the insulation of the power wire is damaged. , so the indoor three-pole power socket must be grounded, so as to prevent the generation of induced electricity and prevent electric leakage and electric shock.
