We have a HOBART HFD50 Fryer 208V 3 phase. The inoperative unit has power to it but when turned on and as soon as the power is sent to the heating coils the unit completely shuts off? No errors indicated?

You have a short or other malfunction in the electrical/electronics/computer system and the system is shutting down on safety systems.

    one further thought, CHECK BETWEEN ALL 3 LEGS, power to ensure 208V, line 1/2, line 1/3, line 2/1, line 2/3, line 3/1, line 3/2. A blown fuse on one leg might very well be your problem!



    A quick way to test the fuses, take one side of your voltmeter and connect it to the metal case. Set the meter to a range capable or reading 208 volts. Your 208 volts might also read 220 volts, or your 220 volts might read 208 volts. Checking from the fuse in to ground should give you between 100 to 120 volts. Check both sides of the fuse hot line to the ground. If you find any fuse/breaker, or wiring connection that doesn't continue to read the 110/120 voltage, that line is open or not carrying power!

Wells deep fryer 208 volt 3 element. 1 element works other two don't working left to right. Continuity good resistance good. Relay problem?


Sounds like this maybe a three phase unit and you are powering it off on single phase power. Most can be converted to single phase but will draw three times the current and requires some wiring changes. It needs to be on a three section breaker for 3 phase.

Tip

Will not power on, powers off, will not heat Pwr light out or goes out.


Like most of the problems listed on FixYa about this Deep Fryer ours worked fine the last time we used it, but we could not get the power light to come on again. I found that there is s SAFETY Micro-switch on the heating element control unit. This switch prevents the heating element from being turned on when it is not in the Fryer Pan. The accuator lever for the switch is located under the guide slides on the heating element control unit. It is a metal lever which is moved as you mount the heating element control unit on the fryer pan. You have to look closely under one of the guide ledges on the heating control unit to see it . The problem is that over time the adjustment of the lever changes as it flexes under use. I simply readjusted the lever by forming it with a pair of long-nosed pliers. CAUTION !!!!!!! You can bend the lever so far that the switch is closed all the time defeating the Safety Switch and create a hazard in that the unit will heat as soon as you plug it in whether inserted in the Fryer Pan or lying out on any surface. This might burn someone or cause a fire. Good Luck

Wells 3 element commercial deep fryer. One element heats up other two do not. So all the work of heating is one element. Eventually the reset button trips off. All three tested good for continuity. Is...


Sounds like you may have a 3 phase fryer, or it is wired wrong. If you only have single phase power, it might be able to be rewired so that all three heaters are on the two main leads, this is often done at the power relay with a strap. Note the current will be much higher this way.

I took the fryer out of storage. Got little response from unit


All element units are pretty simple,and you can think of them, as Heater Element, with a switch, in the Phase, that's Opened/Closed via a Thermostat, (& a sensor for said thermostat), and thus the Power is connected to the element. As such, it is easy to troubleshoot, you need a Multimeter, Using OHMS, Or Continuity test, simply trace out the circuit, from, plug, to element, along the Phase, Black, wire, USA, to the Element, the "Other" side of the Element is simply connected to return, or neutral. Also there is a "Thermal" fuse, that is there to protect, that too may have faulted, all fuses should be short circuit.

Most likely solution is to replace the reset. If the new reset trips, check the amperage on the elements. At 208V all three phases should be around 47A, 480V around 20A each. Check all wiring connectors for good connections and no evidence of corrosion or overheating.

Change 208v heating elements to 240v.


If your supplying 240 vac to a 208 vac element it will work but shorten the life of it.Goto 3wire.com and register,they should have a 208vac element.The wild leg could also be an issue but if you get a 208 vac element it shouldnt hurt it that much.Why you would be getting a reading of 240 vac on l1-l2-l1-l3-l2-l3 is strange.Let me know.

If this is an electric fryer you may have a shorted element that will continue to heat when ever the fryer is turned on,even when it is not calling for heat. If it has 3 phase power, the elements could be wired wrong
