Measuring Amp Draw – PFE-580 and PFE-590
Objective

To identify if there are issues with cooking performance or oil recovery caused from issues
with the heat system. This inspection will be accomplished by measuring amp draw at each of
the 6 heating elements (3 heaters in each of the two heating element assemblies) and
comparing that reading with the "Amps per heater" number found in Table 1. that matches
the voltage of the unit being inspected.
Volts Phase
200 3
208 3
240 3
380 3
400 3
415 3
480 3
Checking Amp Draw for 200, 208, 240 and 480 volt units
units, see next page (Please refer to Figure 1 on the next page for these instructions).
1. With voltage disconnected from the fryer, attach an amp clamp to wire 1 connected to the
secondary contactor at the upper heating element (Figure 1.).
2. Re-connect voltage to the fryer and select a product to allow the fryer to call for heat. Once
heating, make a note of the wire being checked and the amp draw from the amp clamp.
Example: Wire 1 Amp Reading 13.2
3. Repeat steps 1 and 2 for wires 2 and 3 for the upper heater and then for wires 1, 2 and 3 for
the lower heater. Remember to note amp draw for each wire.
4. Compare the noted readings with the "Amps per heater" column in Table 1. that matches the
voltage of the fryer. If all voltage readings are within 10% of this number, the heat circuit is
working properly and passes inspection. If one or several of the wires tested does not match,
troubleshoot to narrow down whether there are issues with incoming voltage, contactor(s),
or heating element assemblies.
