    Hi,
    I have a Kelvinator under counter oven and hob. Plates of hob not working properly and need to change, can I buy only the top and replace or do I need to to buy the whole system (Oven+hob)?

    If I can just but top hob, can I go for different design (current one is metal hot plate) I want to shift to ceramic/glass one?
    please advise.

    Thanks
    regards.

    • Dave Rongey says:

      Hi Jean,
      Replacing the hob plates heating element should be possible through Kelvinator or an authorized supplier, who will also be able to tell you if it is possible to upgrade the hob with the ceramic type plates.
      I hope this helps,
      Dave

    I had purchased an Aroma Double Burner Hot Plate – AHP 313 and now one of the burners is not working. In reading customer reviews of the product someone suggested that the thermal fuse might be broken. Can you please tell me how to replace such a fuse?

    Thank you very much for your assistance,
    Donna Froio

    • Dave Rongey says:

      Hi Donna,
      The thermal fuse for the Aroma AHP-313 Hot Plate is located near the side of the unit. Replace the thermal fuse with one of the same rating and size. Keep in mind that there should be 10 inches of clearance around all sides of the hot plate unit to prevent the thermal fuse from overheating. The thermal fuse is designed to prevent the hot plate from overheating which could cause permanent damage to the unit and its components as well as materials which are too close to the unit.
      I hope this helps,
      Dave

    Please can you assist me with instructions on how to replace the plates on a free standing 4 plate electric Defy stove?

    • Dave Rongey says:

      Hi Lucinda,
      Here are the basics for replacing the heating element plate for a defy stove:
      Identify the make and model for your stove and the heating element to make sure you get the exact replacement part.
      Turn off the electrical circuit for the defy stove or unplug the main power cord before opening or gaining access.
      Acess the burner element and notice the wiring connections and make notes to make sure the replacement is connected the same.
      Remove the wires and carefully remove the existing defy top burner plate.
      Put the replacement plate in position and attach the wiring to the burner plate the same as the original making sure the connections are firmly in place.
      Complete installing the replacement burner plate as the original.
      Carefully close up all access points to the top of the burner plate.
      Restore the electrical circuit power and test the replacement part.
      Be careful and Enjoy!

    I have a 4 burner stove. When I turn on one of the big burners the circuit breaker trips off, but the two small burner elements are working OK even when switched on together. Please help.

    • Dave Rongey says:

      Hi Mooketsi,
      The big stove burner that you are referring to may have one or more problems as described below in order of probability:
      The wiring leading to the large heating element is damaged and needs repairing.
      The stove heating element is defective and needs to be replaced.
      The heating control for the burner and or the electrical wiring connecting to the control is faulty.
      The electrical circuit for the stove should be identified and turned off before any service work is performed.

  6. Louis says:

    I am experiencing this exact problem. The original plates worked 100%. I replace them because they started rusting and the wife complained about the effect on her pots.

    Now the new plates only slightly heats up. Nothing near what is required ?

    • Dave Rongey says:

      Louis,
      I would check to make sure that the new replacement hot plate elements were pressed into the socket all the way and that the wiring leading to the sockets did not get pushed back where they could not connect with the new hot plate elements.
      Dave

  7. H Eraman says:

    I replaced my defy red dot hot plates but it does not heat up beyond warm even if the switch is on 8. What could be the problem.

    • Dave Rongey says:

      Hi H.E.
      You may want to check the circuit breaker. If the unit requires 240 volt then the circuit breaker may only be providing 120 volts, this depends on your voltage in that part of the world. There may also be a problem with the main electrical panel. Was the original defy having the same problem? If so the problem is most likely somewhere in the circuit.
