What to do if EVAPCO Accessories fan motors are overamping?
- R
  robin99Aug 8, 2025
  If EVAPCO Accessories fan motors are overamping, several factors could be responsible. It could be due to a reduction in air static pressure. For a forced draft unit, make sure the pump is on and water is flowing over the coil. If the pump is off, and the unit wasn't designed for dry operation, the motor might over-amp. Also, check the voltage across all three legs of the motor for any electrical issues. Verify the fan rotates correctly, and if not, switch the leads. Ensure the fan and motor turn freely by hand, checking for internal damage or bearing issues. Finally, check for proper belt tension, as extreme tension can cause overamping.

Why is my EVAPCO Accessories motor making unusual noise?
- J
  Jesse HernandezAug 19, 2025
  Unusual motor noise in EVAPCO Accessories can stem from various issues. The motor might be running single-phase; if you stop and try to restart it, it won't start again. Check the wiring, controls, and the motor itself. Incorrectly connected motor leads could also be the culprit, so verify the connections against the wiring diagram on the motor. Bad bearings are another potential cause; check the lubrication and replace the bearings if necessary. An electrical unbalance, where voltage and current are uneven across the three lines, can also lead to unusual noise, so check and correct if needed. Also, inspect for a non-uniform air gap and rotor unbalance and correct bracket fits or bearing, rebalance, reinstall or replace the fan if required.

How to fix an incomplete spray pattern in EVAPCO Accessories?
- H
  Holly HansenAug 29, 2025
  An incomplete spray pattern in EVAPCO Accessories could be due to several reasons. The nozzles might be clogged, in which case you should remove and clean them, and flush the water distribution system. Another possibility is that the pump is running backwards; visually verify the pump rotor rotation by turning the pump off and then on, and verify the amp draw. Inadequate pump flow for a remote sump could also be the issue; confirm the inlet pressure at the header meets recommended valves and adjust the cylinder to provide blade tip clearance. Finally, check for a clogged strainer by removing and cleaning it.
