Delfield Undercounter Refrigerator Cleaning & Maintenance
Keep appliances in top working condition when you stick to routine preventative maintenance. Below we will help guide you through some Delfield undercounter refrigerator maintenance including the essentials like interior, exterior and drawer cleaning.
The following guide is designed for the Delfield 400P & 4000P series and the 4400 & 4500 series.
Interior Cleaning
- Interior - The interior can be cleaned using warm water and a mild soap. If you need something stronger, try ammonia and water or a non-abrasive liquid cleaner. Interior cleaning should always be done on a daily basis, at startup and also after prolonged shutdowns.
- Gasket - These need to be on a daily and monthly basis. Wipe down gaskets with a clean cloth and warm, soapy water to prevent any mold or mildew build-up. Frequently check the gasket for any cracks or rips and replace as needed.
- Drain - Located inside the unit, drains should be checked for any obstruction. These can become loose or disconnected, so check the drain tubes during maintenance.
Exterior Cleaning
- Exterior - Clean the exterior on a daily basis for best practices and to maintain hygiene. Never use steel wool, abrasive pads, chlorinated chemicals, citrus or abrasive cleaners. Use either a stainless steel cleaner or warm, soapy water to wipe down the exterior, making sure to wipe with the grain. Cleaning the exterior should be done on a daily basis, at startup and also after prolonged shutdowns.
- Casters - On a monthly basis, make sure to wipe down casters to prevent any corrosion. Checking the casters frequently will also ensure that you get ahead if any are rusting or breaking.
Condenser Coil Cleaning
- Condenser coils - These should be cleaned on a monthly basis to prevent the build-up of dirt, dust and debris. Use a wire brush or vacuum to clean any build-up from the coils. If you find grease build-up clogging the coils, use a condenser cleaner to help. Make sure to never use a high pressure water wash for the coils, as this could
Drawer Maintenance
Drawer maintenance is essential for smooth track function and needs to be done on a weekly basis.
- Step 1. Remove the drawer - Pull the drawer box until it stops. Lift the drawer up and pull it out completely.
- Step 2. Clean bottom drawer tracks - Use a soft bristle brush to clean the track on the bottom of the drawer box.
- Step 3. Remove drawer tracks - Pull the drawer tracks out until they hit a stop. Push the tab back on the blue safety clips located at the back of the track. Lift up and pull the drawer tracks all the way out of the drawer cage.
- Step 4. Clean tracks - Either run the tracks through the dishwasher or clean them in a sink with mild detergent and a soft bristle brush.
- Step 5. Reassembly tracks - Push the drawer tracks into the drawer cage. Make sure the blue safety clip is pushed towards the back. The blue clip should lock into place. After all tracks are back in, insert the drawer box and push the drawer back in slowly. When the drawer box is about half way in you will hit a stop, then lift the front of the drawer up to continue reinstalling.
