Page 34controller circuit board where the black wire with ayellow trace is connected (test point 14). A reading ofless than 20 V here indicates a faulty controller. If thereading is more than 20 V, turn the rotary switch to"OFF" and then "POOL" or "SPA" again to be surethat the internal contacts are working correctly. Thevoltmeter reading should drop to zero when the switchis "OFF" and return to at least 20 V when the switch isplaced back in the "POOL" or "SPA" position.10.4.7 Gas ValveThe gas valve consists of an internal operatingvalve and a regulator. The valve supplies gas to themain burners for heater operation. The regulatorallows limited adjustment of the manifold pressure.The gas valve will operate only when there is acall for heat, all safety circuits have been satisfied andafter the igniter has been energized. If the gas valvedoes not operate under these conditions, check thevoltage going to the gas valve. Leave the red voltmeterlead at the common terminal of the transformer (testpoint 1). Move the black meter lead to the "valve"terminal on the ignition control where the brown wirefrom the gas valve is connected (test point 20). If thevoltage is not within the range of 20 -28 VAC, checkthat the igniter is energized and glowing. (There is a 40second heat up time between the initial energizing ofthe igniter and the activation of the gas valve). If theigniter is energized, the 40 second heat up time haspassed and the meter does not show 20-28 VAC, thenthe ignition control is faulty and will need to be re-placed. If 20-28 V is shown at test point 20 move theblack lead of the meter to the terminal on the gas valvewhere the brown wire is connected (test point 21).This test point will have voltage present only during atrial for ignition or during normal operation. The metershould read 20-28 Volts. If there is no voltage, thenthere is a bad connection between the gas valve andthe controller. Replace the brown wire.Listen closely to the gas valve when it is firstactivated (24V first appears at test point 21 during thetrial for ignition). There should an audible "click" whenthe valve opens.If there is voltage at test point 21, but the gasvalve does not open, replace the valve.10.4.8 Igniter/Ignition Control CircuitWARNINGThe igniter, power supply circuit board and someterminals of the ignition control utilize 115V or 230Vpower and require appropriate servicing precautions.Note that wires and terminals of these componentsmay be “hot” even when the component is notoperating.AVERTISSEMENTLe dispositif d’allumage, le circuit d’alimentationélectrique et certaines bornes de la commanded’allumage utilisent une tension de 120 V ou de 220V et exigent des précautions appropriées lors duservice d’entretien et de réparation. Notez que les filset les bornes de ces composants peuvent êtrechauds même si le composant ne fonctionne pas.Check the resistance of the igniter. Disconnectthe hot surface igniter form the ignition control and thered wire that leads to the power supply terminal strip.Set your meter to read in the range of 0-100 ohms.Place one lead of the meter in the connector at the endof each of the igniter wires (test points H and I). Theresistance should read between 40 and 75 Ohms atambient air temperature. If the meter reads outside ofthis range or shows an open or short circuit, replacethe igniter.Check the voltage supplied to the igniter. Setyour voltmeter to read in a range to up to 120 VAC.Place one lead of the meter in the connector on theend of the red wire coming from the power supplyterminal strip (test point J). If the heater is suppliedwith 115 VAC, place the other meter lead on the"IGN/120" terminal (test point K) on the ignitioncontrol. The meter should read between 98 and 126VAC. If the heater is supplied with 230 VAC, placethe other meter lead on the "IGN/240" terminal (testpoint L) on the ignition control. The meter should readbetween 98 and 126 VAC if read with a RMS meteror 50-65 VAC if read with a non RMS meter. If themeter shows voltages outside of the correspondingrange, either the ignition control or the red wireconnected to the power supply terminal strip is faulty.Check the red wire, its connections and termi-nals. If the wire is sound, replace the ignition control.SECTION 11.Replacement Parts11.1 Ordering InformationTo order or purchase parts for the Lite2 modelLD pool/spa heater, contact your nearest Jandy dealeror distributor.
