Введение
The aquarium water heating element heats the water of the aquarium and allows the aquarium to achieve and maintain the user’s desired temperature. If said heating element were to fail, the resulting failure would cause the temperature of the aquarium to change, resulting in negative consequences that would require replacement of said component.

-
-
Unplug the device from the outlet and let the heater cool down for 5-10 minutes.
-
Remove the heater from the aquarium.
-
Using a toothbrush and running water, thoroughly scrub the aquarium heater to remove any dirt and grime.
-
Dry the heater with a paper towel.
-
-
-
Move the thermostat switch to the end or to the farthest point it can go.
-
Using a visible colored Sharpie (depending on the color of your device), mark a line as a reference point. As this will not wipe off easily, you will be able to realign any deviations if necessary.
-
-
-
Starting near the bottom , slide the opening tool in between the plastic halves of the heater's dial.
-
Once the tool is in between the two plastic halves, slowly slide the tool up until either the halves separate or you hit a plastic depression clamp.
-
If you have hit the depression clamp, slightly bend the half to see if you can detach the clamp. If you cannot, slightly pull out the opening tool just enough to slide it above the depression clamp while prying the plastic halves apart.
-
Push downward and at a slight angle to detach the depression clamp and the plastic cover.
-
-
-
With two spudgers or opening tools, one small and the other large, carefully and slowly place the smaller one between the rubber stopper and the glass tube. Next, slowly apply pressure with a prying action to free the rubber stopper. Repeat around the stopper to eventually detach it.
-
Once a small portion is lifted continue the prying step, with the larger opener.
-
Stop when about 60%-75% of the rubber stopper is sticking out.
-
-
-
Without twisting or turning, slowly apply a pulling force to separate the glass tube from the core components of the water heater.
-
-
-
-
Locate the foam insert and carefully separate it from the heating pad.
-
Remove the foam insert.
-
-
-
Bend the heating pad back while applying light pressure to the chip to assist separating the two components.
-
Start heating the top pin until it is liquefied and detachable. Remove the pin and set it aside. Repeat this process for the second pin.
-
-
-
Remove any old solder by melting and slightly scraping it off.
-
Insert the new heating element pin into the circuit board hole. Then push and flatten the heating pad.
-
Next, heat the pin to melt new solder to fuse the pin and the board together. Repeat this step for the other side.
-
Once finished, slide the circuit board chip back into the plastic housing of the heater.
-
-
-
Hold the heating pad down to position the chip inside the housing. You may need to press the wires down to close the casing. Repeat this process again for the other cable.
-
-
-
Re-insert the foam insert back into the heating pad.
-
Compress the heating core enough to fit back into the glass tube. Stop inserting once you hit the rubber stopper.
-
-
-
To easily reinsert the rubber stopper, it is recommended to use a form of grease.
-
Apply pressure until the rubber stopper is fully depressed.
-
-
-
Reattach the plastic housing, making sure that the previously marked heating switch is properly aligned.
-
