Heater contactors "buzzing": Do you mean normal buzzing or extra loud buzzing? Loud buzzing or chattering can be caused by low voltage to a contactor. If normal sounds, then probably the relays on the contactors is working, but the contacts may be stuck, or burned enough so as not to make contact. First, get a voltmeter and check for 240 volts AC at the heater contactor terminals. If the voltage is low, most likely you need to check the contactors further. Check for dirty contacts, clean if needed. If the contacts are not moving when energized, then you will probably need to replace one or both of the contactors.

You need to check your temp sensor and your high limit. Both are tubes that slide into the plumbing on or near your heater. If this is a tube heater then they are probally at on each end of the heater and will have small wires coming from them that go back to the control board. Farely common problem and easy enough to fix with replaceing them both. A number of models wire them together so they come as one part. Good luck.
