Thermal fuse specs for HP3150 fuser assembly

It is very possible that your larger thermal fuse may provide inadequate protection, because it will have more thermal mass and thus take more time to heat up, i.e. in a locked rotor condition, and could allow the windings to overheat and burn before the fuse melts.

This safety device protects the appliance from overheating and potentially damaging the motor or other sensitive components. If your gas or electric dryer begins to overheat, the thermal fuse is designed to open, or “blow”, interrupting the voltage and preventing power from reaching the motor and heating components.

Thermal Fuse – 125C Trip Temperature – Ceramic

It is IEC rated for use at up to 15 amps at 250 volts. It serves to open a circuit when temperatures rise above a predetermined value.

When it turns liquidous, it causes the fuse to open. This means that any good thermal fuse should read “0” ohms across it, whether in or out of the circuit (like the others have said). If you get a large resistance across one of these, it has opened and needs to be replaced.

Thermal fuses are not one size fits all, and you need to have the specific fuse that your model of dryer uses. Once a replacement has been retrieved, start by unplugging your dryer and removing the back panel. The thermal fuse will be located somewhere by the exhaust vent on your dryer.

Temporarily tape the two wires that go to the thermal fuse together to essentially “bypass” or “jump” the thermal fuse. Use electrical tape to properly insulate the connection and avoid contact of bare wire contacts with the dryer cabinet.

Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature.

NO! A Current Fuse is to protect equipment from shorts. The 10A mark you see on the thermal fuse is to show the maximum current the thermal fuse is rated at passing. Look for the Temperature mark and replace with same values.

Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse. However washing machines, dishwashers, microwaves, kettles, toasters and irons usually require 13 amp fuses.

The amp rating of a fuse normally should not exceed the current carrying capacity of the circuit. For instance, if a conductor is rated to carry 20A, a 20A fuse is the largest that should be used.

The ampere rating is almost always shown on the fuse and is usually expressed in amperes (eg. 10A or 0.5A), but it could also be expressed in milliamps (eg. 100mA). Sometimes the ampere rating is incorporated into the fuse part number eg.

Choose a fusible resistor that has a power rating as close as possible to your intended power rating, without being higher than it. V = I x R, where V is voltage, I is current, and R is resistance.

The reading for a working thermal fuse should be zero– meaning that this thermal fuse is working perfectly and doesn`t need to be replaced.

WARNING: Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire. If electrical components in the vehicle are not working, a fuse may have blown.

The higher the ambient temperature, the hotter the fuse will operate, and the shorter its life will be. Conversely, operating at a lower temperature will prolong fuse life. A fuse also runs hotter as the normal operating current approaches or exceeds the rating of the selected fuse.
