What to do if my DeWalt DXH190HD Heater is unable to detect flame?
If your DeWalt Heater can't detect a flame, try these steps: * Inspect the wiring to the cad cell using the wiring schematic in the manual. * Clean the cad cell photo cell. * If the heater still doesn't work, replace the cad cell.
How to troubleshoot a DeWalt DXH190HD Heater that has no spark?
If your DeWalt Heater has no spark, consider the following: * Check the extension cord's length and gauge to ensure it meets the amp requirements (refer to page 5). * Inspect the wiring to the igniter using the wiring schematic in the manual. * Verify the gap between the electrode probes is between 2.3 and 3 mm. * If there's still no spark, replace the igniter assembly.
Why does my DeWalt DXH190HD Heater motor overheat or stop?
If your DeWalt Heater's motor overheats or stops, here are some things to check: * The motor speed may be too low (it should operate at 3450rpm, except for the 50K model at 1550rpms). If so, replace the motor. * With the heater disconnected from the AC source, rotate the fan clockwise to verify the motor is free. * Remove the air filter housing from the motor and inspect the pump rotor for damage; replace the rotor assembly if damaged. * If the wiring is correct, the pump rotor is okay, and the motor is not rotating freely, replace the motor or power-pack assembly.
What to do if my DeWalt DXH190HD Heater cannot detect the flame?
If your DeWalt Heater is unable to detect a flame: * Check the wiring to the cad cell using the wiring schematic in the manual. * Clean the cad cell photo cell by sliding it out of the holder, pushing the photo cell out of the rubber housing, cleaning it with a soft cloth and rubbing alcohol, and reinstalling it. * If the heater still doesn't operate, replace the cad cell.

How to fix a DeWalt DXH190HD Heater when there is no spark?
If your DeWalt Heater isn't sparking, consider the following: * Verify the extension cord's length and gauge are appropriate for the amp draw. Check the requirements on page 5 of the manual. * Inspect the wiring to the igniter using the wiring schematic in the manual. * Confirm the gap between the electrode probes is within the range of 2.3 to 3 mm. * If there's still no spark, replace the igniter assembly.
Why does the motor in my DeWalt DXH190HD Heater overheat or stop?
If the motor in your DeWalt Heater is overheating or stopping, it could be due to the following reasons: * The motor speed is too low, in which case you should replace the motor. * The motor may not be rotating freely. Disconnect the heater from the AC source and rotate the fan clockwise to check. * There might be damage to the pump rotor. Remove the air filter housing and inspect the pump rotor; replace if necessary. * If the wiring is correct, the pump rotor is okay, and the motor is still not rotating freely, replace the motor or power-pack assembly.
How to reset the high limit switch on a DeWalt Heater?
