-
Symptom:
The bag does not seal.
-
Cause:
The Seal Bar Heating Element may be damaged. Carefully peel back the tape covering the heating
element and visually check for damage. Replace in needed.
NOTE:
Damage is more likely to occur at the crimps on each side of the heating element.
-Cause:
Loose power connection. Check the seal bar quick connect on the PCB.
-
Cause:
Bad interlock switch. The interlock switch that prevents the heater from being activated when the
vacuum chamber lid is open may be damaged, using a multimeter verify the switch is functioning
properly. See repair guide below.
-Cause:
No power to Seal Bar Heating Element.
1) Remove the upper housing (see repair guide below)
2) Simulate a sealing cycle by running the unit without a bag.
After the Vacuum indicator goes out on the control panel the Seal Bar Element should energize,
using a multimeter measure the voltage at the heating element quick connect on the PCB
(labeled X5 SEAL). You should measure approximately 27VAC. If no voltage is present,
replace the transformer.
-Symptom:
The bag seal pulls apart.
-Cause:
The seal of the bag may be incomplete. If the seal has a crease in it, or if a liquid or powder has
been trapped between the layers of the bag, the layers may not have been sealed together
properly. Cut off the seal and wipe the inside of the bag clean, then try to vacuum-seal the bag
again.
TIP:
When sealing a moist or powdery food, you can double seal the bag by pulling the bag
out of the chamber slightly then sealing the bag again.
-Symptom:
The vacuum pump starts, but no air is being removed from the heat-seal bag.
-Cause:
Vacuum chamber not sealing. Make sure to firmly press down on the vacuum chamber lid
throughout the vacuum-sealing process.
-Cause:
Damaged vacuum chamber seals. Visual inspect the seals for damage, replace as needed.
-Cause:
Improper bag insertion. The open end of the bag should be centered within the vacuum chamber.
Make sure the bag does not to cover the vacuum ports in the vacuum chamber. If you are using a
bag that was made from a roll of material, double-check that the end of the bag is sealed.
-Cause:
Damaged bag. Check for tears or punctures in the bag. If there is a leak in the bag, air will be
pulled into the bag from the outside.
TIP:
For best results, use Hamilton Beach Heat-Seal bags.
-Symptom:
Air is being removed from bag but it appears to be leaving more air in the bag that usual.
-Cause:
Damaged exhaust valve, replace as needed.
-Symptom:
No air is pulled out of the bag and the Vacuum pump does not appear to be working. (no sound
after pressing start).
-Cause:
Damaged vacuum pump. To verify, first visually inspect and secure all connectors then use a
multimeter to measure the voltage present at the vacuum pump quick connect on the PCB (labeled
X4 pump). You should measure approximately 120 VAC. If voltage is present but the vacuum
pump does not run, replace vacuum pump.
-Symptom:
Noise can be heard coming from the machine when it is not in use.
-Cause:
The machine is equipped with a cooling fan for the electronics and vacuum pump that runs when
it is plugged in and powered on.
TIP:
When not in use, turn the machine off and unplug.
