What to do if Enviro Fan heater with SSR does not operate?
If your Enviro Fan heater with SSR does not operate, verify the signal input to ensure the correct signal is being applied. Also, check if the interface board fuse is blown and replace it if necessary.
What causes low or high temperature rise in Enviro Fan?
If your Enviro Fan experiences low or high temperature rise, check the wiring for an incompatible thermostat or controller. Also, check the location of the thermostat, as it might be installed in a location that is either too hot or too cold, and check the heat outputs on the controller if there are problems with additional stages. Finally, check for blocked ducts or the location of the heater if the CFM is incorrect.
What causes low coil capacity in Enviro Fan?
If your Enviro Fan experiences low coil capacity, begin by checking the fan’s operating conditions to ensure correct airflow. Also, inspect the water pumps, valves, and lines for any obstructions that may be causing incorrect GPM. Clean the coil fins and replace the filter if it’s dirty. Finally, make sure the water temperature is correct.
Why is my Enviro Fan motor making excessive noise?
Excessive noise in your Enviro Fan motor can stem from a few sources. Start by tightening the motor mounting bolts, as they may have become loose. If the fan wheel is rubbing against the fan housing, realign the wheel within the housing. Also, check if the fan wheel is loose, and if so, align and tighten it. Lastly, if the SCR is set too low, select a lower tap to reduce the motor speed and readjust the fan SCR.
What to do if Enviro Fan heater does not operate?
If your Enviro Fan heater does not operate, begin by checking the disconnect to ensure there is power. Then, check the transformer and transformer fusing (if applicable), and replace if necessary, to ensure there is control voltage. Also, replace any blown fuses. If those aren't the problem, replace or reset any open limits (primary or secondary), as applicable. Verify the airflow direction by checking the sensing tube (red tube = high, black tube = low) and rotate if needed. Ensure adequate airflow by increasing it to obtain a minimum of .1 in. w.c. external static if low external static pressure is the cause. Finally, inspect the elements for damage and replace as necessary.
How to troubleshoot Enviro Fan motor that fails to start?
If the Enviro Fan motor fails to start, it might be due to a blown fuse or an open circuit breaker. In this case, replace the fuse or reset the circuit breaker, and make sure to correct any source of overload. Another potential cause is a shipping cardboard insert in the fan wheel; remove it and restart the fan. Also, check the wiring connections against the diagram provided with the unit to ensure they are correct. It's also possible that the current supply is not adequate, compare the actual supply power with the motor nameplate recommendations and contact your power company if adjustments are needed. Finally, there may be a mechanical failure, so check the motor to confirm that it rotates freely.
