The LFP-NEWTSPCBOARD is the appropriate replacement electronic control board for Covenant touchscreen electric fireplaces like the WD914-40LT, provided your unit features a touchscreen-style control panel. If your fireplace uses an older physical push-button control style, a different board may be required. To ensure compatibility, it is best to by sending a photo of the fireplace control panel and model/data label. This helps confirm the correct part before ordering. The LFP-NEWTSPCBOARD is available for purchase on Elkhart RV Parts' website, and you can save $5 on your order using code ALIRVP.
