8.0 Troubleshooting Without The Control Panel
•
Diagnostic Tools for Sections 8.1A - 8.1E:
Clamp-on ammeter, voltmeter and ohmmeter.
• Suggested Spare Parts for Sections 8.1A - 8.1E:
Circuit board, control panel, temperature sensor, flow
switch, heater assembly, hi-limit, circulation pump. Refer to page 59 for additional information.
.1A No Heat Or Not Enough Heat
•
Symptoms:
Circulation pump (heating pump) is moving water, panel heat indicator is lit.
Water is not get-
ting hot.
•
Configuration:
Protech LED system heaters will not operate with one or both jet pumps running in high
speed if the circuit board is configured for 40 or 50 Amp operation. See section 6.1, page 23.
Standard Troubleshooting Approach
Danger: Electrical Shock Hazard Exists!
High Voltage Present On Circuit Board. Use
Extreme Caution While Servicing Circuit Board.
** Warning: heater temperature may have
exceeded 130ºF (54ºC). Inspect heater. Call
technical support if visible damage is apparent.
Turn up temperature setpoint
to initiate a heat call (must be
in “Standard Mode” F0-F3; see
page 21). Is voltage present at the
heater output?
Is voltage present at heater input?
Replace or reconnect wires
between heater input relay
and TB1 (main power terminal
block).
No
Yes
Replace circuit board.
Is there current draw? Refer to
section A3 (page 47) for expected
heater current consumption
values.
Check heater element with clamp-
on ammeter around one of the
heater element wires.
Is the heater element’s current
draw within ±10% of its listed
value?
Locate thermal switch inside heater
box. Set voltage meter to 500-1000
VAC range. Test thermal switch by
connecting voltage meter across the
terminals with a heat call present
(see fig. D). If 120 VAC* or 240 VAC
exists, the switch is open. If no volt-
age exists, the switch is closed. Is the
switch open?
*Convertible J-315 models only.
Replace or reconnect wires be-
tween heater output and heater
element. Retest Heater
Replace Thermal Switch. Retest
Heater.
Place thermometer against heater
housing and verify temperature. Is
temperature above 130ºF?
Current draw is proof that heater
element is working. Make sure
customer knows how to use con-
trol panel and heater. Ask about
any possible error messages.
